5 years agoNice and beautiful, I want one!

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

5 years agoA set of technical solutions for the frame, battery placement and folding hinge – bravo to the designer!👍💪👏
ReplyCourt
5 years agoYeah, I agree that it’s a nice design. Thanks for your comment :)

4 years agoIs this bike suitable for tall riders? I’m 6’5″
ReplyCourt
4 years agoHi 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 ;)

3 years agoI 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?
ReplyCourt
3 years agoI 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!!
ReplyMichael
3 years agoThis bike looks great, I’m sure I’ll get one. can’t find any info on warranty. Does anyone have any information?
ReplyCourt
3 years agoHi 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!

3 years agoStay 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.
ReplyCourt
3 years agoI’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 :/

3 years agoI 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.

2 years agoNo controller on the kahuna? Why would synergy comment to utter nonsense like that?
