A full suspension folding fat tire electric bike, available in three timeless colors (dark blue, black, white). Powerful 750 watt Bafang geared hub motor feels very zippy and capable. Hydraulic disc brakes require less hand effort and offer adjustable-reach levers. Both brake levers also have motor inhibitors for safer stopping
Bright dual-beam headlight keeps you seen from multiple angles. No reflective paint or tire stripes here, but the white frame increases rider visibility. Optional $120 rear rack comes with a light mounted at the Back. They include a decent phone mount for free, Synergy also sells aluminum alloy and plastic fenders for $100 or rack fender combo for $150
Sturdy and large folding aluminum alloy pedals from Wellgo, great kickstand placement (with adjustable length), decent Shimano Altus derailleur, limited 14-28 tooth freewheel and slightly large 54 tooth chainring makes starting and climbing a bit slow and difficult
They key must be inserted and left in the frame in order to power the bike on... and the locking core is below the main tube, making it difficult to see and reach. Noticed some delay in starting and stopping using pedal assist, even though the cadence sensor hardware looked pretty nice (compact sealed design at bottom bracket), no torque arm or derailleur guard

To run the forums, host the website, and travel, I charge a universal service fee for my reviews. This in-depth review was sponsored by Synergy Electric Bikes. My goal is to be transparent and unbiased with you, this video and writeup are not meant to be an endorsement of Synergy products. I welcome your corrections, additions, and feedback in the comments below and the Synergy electric bike forums.

Observations:

Synergy is a brand that produces electric kick scooters and electric bikes. They fall under the North 49 brand which owns Vintage Iron Cycles (the shop in Vancouver where I filmed the bike). All of these brands are new to me, and it was a little confusing at first, but the bike performed well and used recognizable parts that I trust
I was told that Synergy offers a one year warranty against manufacture defects. If you buy from the Vintage Iron ebike shop (or one of their ~50 dealers) the bike will be fully assembled, otherwise they offer free shipping to the contiguous US and Canada but you’ll have to do some minor assembly yourself
What really stood out to me about this product is that it’s a full suspension folding fat bike… that’s a pretty unique offering that’s very rare. The rear suspension is kind of basic, and the frame is made longer to accommodate the rear swing arm, but it did reduce back and neck sensitivity for me while riding. Given the higher 300lb (136kg) max weight rating and long 450mm seat post, this would be a great electric bike for taller or bigger riders who want portability as well as full leg extension

Pros:

This is one of the only folding electric bikes I’ve ever seen with full suspension… let alone being a fat bike. It’s pretty comfortable by default but you could always lower the air pressure or adjust compression and preload on the front shock to really dial it in. Having rear suspension reduces knee pressure if you stand up vs. a suspension seat post which only reduces your torso, shoulders, neck, and arm pressure
The bike only comes in one frame size, but the extra long 450mm seat post, telescoping stem (with 100mm travel) make it pretty versatile. It’s a good option for taller riders because of the 300lb max weight rating and longer frame (due to rear suspension design)
Available in three good looking colors. Black is the most seamless because the hardware and cables are all black by default, so they don’t stand out. White will be the most visible from the side, increasing safety. Apparently blue is pretty popular, and creates variety in a world with so many black or white ebikes. This makes the bike fun for a his/hers setup or so friends can keep their bikes separate and unique. The satin paint leans a bit matte, but looks good and shouldn’t so too many finger prints
The battery and controller are both mounted inside the frame, so they’re well protected and the aesthetic of the bike is fairly clean and streamlined
I like that the Kahuna comes with a phone mount and has a full sized USB Type-A charging port built into the base of the display panel! This means you could easily use your phone for GPS directions while charging it
Considering it’s a full suspension ebike with fat tires, I was kind of surprised that the bike only weighs ~65lbs because similar competing products weigh more… however, some of them include a rack or fenders. If you do add fenders, the plastic ones will probably be lighter than aluminum alloy
I was excited to see that Synergy chose trigger shifters here, even with a twist throttle on the right! Usually, there isn’t enough room for this because throttle housings and cables limit mounting options for brakes and shifters. I like triggers because they are a bit quicker to shift with and don’t compromise my hand position while riding. There is room for improvement here however, because the high lever requires index finger action vs. a two-way trigger that could be pushed by the thumb or index finger
The headlight is pretty great! It has two powerful beams and a lens that shines out from the sides a little bit to help improve visibility. Even though the bike doesn’t come with a rear light unless you pay $120 for the rear rack, I love that the rear light also plugs into the main battery pack. This means you won’t need independent disposable cells and won’t have an extra step to turn either light off when you stop the bike
The full sized 20″ x 4″ fat tires provide stability, cushion, and they lower the attack angle of the wheels which improves comfort. The tread pattern wasn’t so knobby that it made a lot of noise on the concrete, but did provide good traction for my rides through dirt and sand
Despite being fairly large and heavy, the weight on this electric bicycle is positioned well and the frame didn’t feel flexy. Sometimes, suspension can add a feeling of flex and looseness to steering and handling, but that also wasn’t an issue for me here
The motor is very powerful and capable! Planetary geared hub motors work very well with throttles, they coast without producing any drag, and they start with a lot of torque compared to gearless hub motors. Since this ebike has smaller 20″ diameter wheels (probably closer to 24″ with the fat tires) the hub motor gets a mechanical advantage compared to a larger 26″ or 28″ wheel
Both of the frame folding points (at the center of the frame and on the stem) have a locking mechanism for safety when riding, this way, they won’t come completely unfolded if the clamp becomes loose
I love that the LCD display panel is fairly large, has adjustable backlight brightness, and offers a full size USB charging port built into the bottom (providing 5 volts and a full 1 amp of power). This is very convenient if you are using the included phone mount with your smartphone for GPS and need a bit of extra juice for your smartphone on long rides… the phone holder they chose worked very well for me during the test ride :)
I’m glad that the LCD display isn’t programmed with so many options here. I’ve seen this same hardware used on other ebikes that allow you to select the power level, and it’s just one more step that can create confusion. This one just has five levels of assist and the power level increases automatically as you go from 1-5
The display is large, easy to read, and has plenty of good readouts… though I wish it had 10 bars for the battery infographic or used a percentage vs. 5 bars. It’s not removable, but can be swiveled to reduce glare or add protection when folding the bike
Synergy chose a sealed cadence sensor that’s less likely to get blocked by mud or kicked out of position. It’s mounted around the crank spindle on the left side of the bike
The twist throttle design is excellent here, because it lets you override all five levels of assist with near-full power. This means that you can ride in assist 1 or 2 (which are still very powerful) and then override for speed or extra power on a hill climb without pushing any buttons, simply twisting the throttle
The kickstand is adjustable, has a wide platform at the bottom to keep it from sinking in to soft terrain, and it works well if you’re loading the bike with gear. Note that the kickstand is positioned far enough back that it won’t cause pedal lock when backing the bike out, or cause heel strikes when pedaling
Both wheels are built with thicker 13 and 12 gauge spokes for increased durability and weight capacity. I appreciate that Synergy chose to paint the spokes black on the Kahuna models to blend in with the rims and hubs. Note that the official max weight rating is a higher than average 300 pounds (~136 kilograms)
The bike comes with free shipping for most locations in the US and Canada, which is great! Sometimes, shipping is an additional $100+ cost, so it feels like there’s a lot of value with this product. The one year warranty seems decent as well, even though this is a fairly new company to me… they had a nice headquarters location with lots of bikes and a very friendly staff :)

Cons:

I like the physical design of the cadence sensor, because it’s compact and sealed, but the configuration seemed a bit delayed… it took a moment for the motor to kick in when I pedaled and another moment to stop when I ceased pedaling. Good thing both brake levers have motor inhibitor switches built-in for safer stopping
With such big tires, heavy rims, and a powerful 750 watt hub motor, I feel that the bike could benefit from a torque arm on the rear axle. As it stands, the flat portions of the rear axle and torque washers seem to do a good job, but it wouldn’t add much weight to have a full torque arm. As an end user, make sure the rear portion of the bike is setup correctly and the bolts are sufficiently tight so you don’t end up with rocking and have the steel axle chew into the aluminum alloy dropouts. I’ve had this happen when I fixed a flat tire or did some derailleur/freewheel maintenance and didn’t do a great job tightening things up afterwards
I suspect that a good portion of sales for this product will be made online-direct, even though Synergy claims to have over 50 dealers (which is awesome!) so it would have been nice to see a derailleur guard to protect the derailleur cable, derailleur, and motor power cable during shipping and during use… especially when folded. They could also include a velcro strap, rubber band system, or magnets to keep the bike folded securely since rattling can chip the paint (velcro strap is probably the cheapest and most effective with such a large frame, consider an aftermarket bungee cord with plastic hooks that won’t scratch the paint for your own solution)
You definitely pay a premium for the full-suspension setup and hydraulic disc brakes here, and the price continues to rise if you want fenders and a rear rack ($150 if purchased together or $100 individually). I noticed that the rear fender connects near the bottom bracket and up at the seat stays, but then extends pretty far without any support… it made me wonder if it rattles or would clink against the optional rear rack if you got it (since the rack surrounds the fender pretty close)
This bike has a bit more exposed wiring, and the wires are not internally routed. Visually, it’s a negative, but physically it’s less vulnerable given the folding frame design
I love that the bike has a good quality headlight with bright beams that can be seen from the sides, but there’s no rear light unless you buy the rack (at least it’s wired in though! There’s a little connector cable near the seat tube). I didn’t see any reflective paint or stickers on the frame, no reflective stripes on the tires, and the tires didn’t seem to have puncture protection… so consider using Slime or some tire liners
In order to power on the display, you first have to insert the key below the main tube and twist to “on” which requires some bending down and fiddling. It’s not as convenient as a side-mounted locking core, and I wish you could remove the key so it could be kept on a keychain
Basic 2 amp battery charger means it takes longer to refill the bike than a 3 amp or 4 amp charger, but it’s fairly lightweight and I’ve seen D-Power before, so it should be cheap to replace or get an extra if needed (one at home, one at work for example)
With a limited freewheel offering 14 to 28 tooth (vs. 11 to 32+) and a very large 54 tooth chainring, this ebike can be slower and more difficult to start from standstill or climb with, even in the lowest gear
You have to fold the bike in order to reach the battery for removal and independent charging. I feel like many people will just leave it in the frame and plug in near the folding joint… but keep the battery in a cool dry location if possible because extreme heat will degrade the cells and extreme cold will limit your range temporarily
The main folding joint on the downtube is pretty wide. That makes it sturdy, but also creates the potential for banging a knee or thigh (which happened to my girlfriend once on a similar ebike, leaving a bruise)
Keep an eye on the front cables when the stem is fully extended, if you stretch them out too far it can impact steering or unplug the wires. Same thing goes for folding the bike, try not to pinch the cables and make sure the stem is all the way down to achieve the most compact size
The display is large and easy to read but not removable, so it could take extra weather wear and possibly get scratched at a bike rack. I appreciate that the bike can be completely disabled by turning the key to the locked-off position when parking at racks, so nobody can tamper with it.
I love that you can enter into the display settings area and adjust units by holding the set button (press set again to navigate through four menus there including speed adjust), but I wish there was more feedback about range and remaining battery capacity, it only shows five bars which relay 20% steps vs. 10 bars or a full 100% readout
Minor considerations here, the headlight is mounted to the lower portion of the suspension fork and will bounce up and down when you ride over bumpy terrain. This would not happen if it was mounted to the stem or handlebars… and it would be much higher and more visible there as well (but possibly prone to damage when folding/transporting).
The clear plastic slap guard on my demo unit was peeling at the edges and didn’t quite protect the right chainstay. I think it would be nice if they included a bell with the bike, even a simple one :)
I didn’t see a mounting point for adding a bottle cage on the frame. You could always get the optional rear rack and use a trunk bag with a bottle holster… I can see why maybe they skipped bottle mounts, since the frame tubing is almost horizontal, and the bottle could drip, but they can also be used for folding locks and other accessories, so it’s still missed a little
Minor consideration here, the weight of the bike could be decreased and the comfort plushness of the tires increased if they used punched out rims. This is something I’ve seen on a few other fat tire ebikes, and it would also save material, so I like to point it out as a possible future upgrade they could do

Nice and beautiful, I want one!

Court

Hey Mendovan, I agree with you… and it’s comfortable and capable off-road. Nice combination ;)

Віктор Ігорович

A set of technical solutions for the frame, battery placement and folding hinge – bravo to the designer!👍💪👏

Yeah, I agree that it’s a nice design. Thanks for your comment :)

Is this bike suitable for tall riders? I’m 6’5″

Hi Chris! I think it’s doable, but most value folding ebikes that only come in one size are built for “one size fits all” and are geared more towards a 5’5″ rider. I’m 5’9″ and it worked just fine. If you raise the seat and handlebars, it should work alright. The thing is, you might feel squished horizontally. Like, if you aren’t getting maximum seat height to get that full leg extension (since the seat post has a height limit) and the same thing happens for the handlebar, and you’re not able to extend reach somehow, you may feel hunched over. I would recommend swapping the stem, but this bike has a steer post + stem combination, so that’s not an option. You might consider switching the handlebar to a high-rise design vs. flat, but then the electronic wires, shifter cables, and brake lines might not reach. Frankly, most one-size ebikes are going to put you in a very similar position. I think it could still be a lot of fun for you, it’s just hard for me to recommend it unconditionally because I do think it will feel a little squished. You could ask Synergy directly, or ask in the Synergy forums, but that’s my two-cents ;)

I am considering this bike or the Voltbike Mariner. I would have to wait 6 weeks for the Mariner but the Kahuna is available now for $1000 more. I know you have tried both. Which one would you choose?

I liked the full suspension setup here, but am more familiar with Voltbike. I think you’re correct that both would fit the bill. Perhaps it comes down to which model looks cooler to you, or maybe what’s in stock since so many have been sold out!!

Michael

This bike looks great, I’m sure I’ll get one. can’t find any info on warranty. Does anyone have any information?

Hi Michael! Yeah, I really like how this one looks… and it performed pretty well during my ride tests! The warranty information that I was provided with is “1 Year Manufacturer Defect” and it seems that availability is fairly limited, but they are trying to add dealers from their website. Perhaps you can contact them directly for more info? Good luck!

Stay away from this rebranded over priced Chinese bike you will not get the parts that are supposed to be on it this goes from top to bottom of the bike the Rims are a split rim of some nature that are not true and as to the hop of the non kenda tires . The brakes are not tektro and are 35 dollar plastic line pull hydraulic with terrible calipers and I mean plastic lines no lining on these puppies which are going to snap in the snow which it is advertised to be able to go in.160 rotors when most rebrands of this style offer 180 in the front . It comes with a 12ah controller 25 amp Max but it doesn’t like it. No kenda tires here either I’ve gotten cts which do not like to sit on these rims straight causing it to bounce. There is a severely underrated fork which states it is not for any trail riding and a rake to match. The fluid has leaked out of it already slowly through the seals no jumping or horsing around required. The steering stem is a dated threaded style which is also under rated with open bearings and whatever plastic spacers they had laying around to fill the gaps it seems. Making it sloppy at the best of times amd like I said no jumping or horsing around required and appears to me of a very low quality steal that majority of the bike is also made of that being the parts that are supposed to be steel and not aluminum axels swing arm pins steering stem even the pin for the folding mechanism is not. According to my high test magnet I realize this is an aluminum build however these pieces that should be magnetic or hold one does so barely and I know it’s not a titanium metal either as it’s soft as hell. Axels and swing arm pins are all made from this same very soft metal aswell. The Shimano drive train was also swapped to a 12 dollar derailleur and shifters to match. The cable for the shifters was the strongest piece of metal on the whole bike FYI. The front handle bars are of concern and have pulled off the bike when it was sleeping I woke up the next morning. The controller I was also told was water proof or at least resistant and I’m glad I checked as it is far from it. It is also only a 12amp continuos controller that will handle 25 for about 15 seconds with the tires blown up so hard that you think they are going to pop. The seat supports have bent and I’m only about 170 lbs and like I said no jumps or horsing around was involved. Bearings all had to be repacked and the solid axels and bearing ends are as cheap as they come you will not want a wheel to come even a half a thread loose or you will start having pieces of bearing falling out. The headlight did not work when I got it home. The battery also could not be turned off. I know there are other dealers of this bike which provide the stated options as advertised the handle bars and even down to the very poorly welded frame which has perosity and what looks to enter beginning of a crack. The poor handle bars feel like I could rip them off at an abrupt stop. All and all shame on synergy for selling the 600 dollar model of this rebrand at a premium price. Last key point is the pins holding the folding mechanism together which is about a four inch hinge is coupled together with a pin less than half that length meaning it’s sloppy as hell. Not sure what to do with this bike I’ve been so frustrated with it. I’ve quite literally had to rebuild it pretty well. I requested a new proper bike from them but have not fulfilled my wishes. I need the bike for transportation so not having it is a huge inconceince . However so is the what seems to be bike repair shop set up in my kitchen every morning.last but not least the paint is listed as a matte white however it should say primer. There are even brush strokes on the front fork from being painted with a brush,I kid you not. Look at getting lectric as they seem to have spent the money to offer a quality product for the price but this is just an insult and a rip off.

I’m so sorry to hear that this has been a frustrating experience for you. Thanks for taking a moment to share the parts that failed and how you feel. Perhaps this will lead the company to produce a better product, or others to know that it’s a more “affordable” ebike with some parts that could fail faster. I hope your next ebike is better :/

Trent

I might add that the battery also does not have a battery control module I have discovered making it like an old dewalt nicad battery that has lots of get up and go off the start cut drain it down to about 75 percent and she’s like a dog slow as hell. It also makes me nervous as I cant leave it plugged in as it never turns green on the charger meaning it could potentially cause a fire if not monitored or left to charge for any length of time. I was quoted nearly 1,000 dollars for a battery for this thing when I’ve found them for around 200 bucks which sure this is what I’ve got.

Has anyone ever seen a battery without a control module from my understanding it monitors recharge and discharge rates and also tells the charger when Togo green and shut down. Quite literally stay away from this bike I realize there’s budget but to are also rebrands of the same frame being sold with the actual parts listed and then some. Quietkat had I don’t know if it’s still available but it had all the listed parts and kid 203 rotors and a 1000w motor for close to the same amount as well an air fork is memory serves me. This is just flat out highway robbery. Yet no comment from synergy here.

No controller on the kahuna? Why would synergy comment to utter nonsense like that?
