8 years agoI love these cross over type bikes. I think many people that buy electric bikes end up going more places than they anticipated and this seems to be one of those bikes that can go anywhere and do almost anything. I love the versatility.
ReplyCourt Rye
8 years agoRight on, I agree completely and frequently hear shop owners like yourself talking about how their customers ride more frequently and further than before they had pedal assist. Normal bikes are great but once you can go further and don’t have to deal with hills or the wind etc. it opens up a whole range of possibilities! including a bit of off-road perhaps ;)
ReplyTony Gandolfo
8 years agoHow do you think this bike could handle on very steep mountain roads?
ReplyCourt Rye
8 years agoHi Tony, are you talking about paved roads or dirt and rock? It’s designed to be sturdy (to handle the higher top speeds) but still comfortable with the suspension and larger tires. The tires it comes with appear to be a checkered hybrid style that can handle street and trails (packed dirt mostly). They won’t be ideal for one or the other… the knobs are too flat to be optimal for hard core mountain biking and not slick enough to be truly perfect for tarmac (pavement). You could always swap them out but given the rest of the bike (lockout on the fork, overbuilt axels and the balanced weight) I’d say it should do very well. I hope this helps, feel free to elaborate and I’ll do my best to sound it out with you :)

8 years agoI am looking for a bike that can handle my daily commute. I would be traveling about 30 miles a day, part of that being a mile long stretch of paved road at a 3.5% grade. I am a fit and active cyclist, however not a proffesional. Do you think this bike could handle such a feat with an average rider such as myself?
ReplyCourt Rye
8 years agoHi Tony, that’s quite a ride! but yes, I do believe this bike would be able to handle it. You will have to pedal along and switch up to the higher assist levels for the incline but it’s well equipped to handle that sort of thing. This model uses the Bosch Performance Speed motor which isn’t quite as high-torque as the CX but it does go faster and 60 Nm is still a LOT of torque. If you’re worried about range, you could top the battery off at your destination (if they allow) the charger is relatively small and light. Also, in the future you’ll be able to find and replace the pack easier than a lot of the other bikes and it looks like it already comes with the upgraded 500 watt hour pack vs. the older 400 watt hour… pretty sweet :)

7 years agoJust received my new Bulls Six50 E2 Street from Propel Electric Bikes in Brooklyn.
I live in Olympia, Washington so the bike traveled across the USA. Shipping went fine. No dents, scratches, or anything wrong. The only small inconvenience is that I can only seem to find one screw out of two for the headlight assembly so it’s off to the hardware store to find a match. It would have been an improvement if the screws were put in a plastic bag. They’re small and probably the one fell out of the box through an open corner. Small deal.
First impressions. It just wants to go! It also rides surprisingly well without any assist. Much better than I would have imagined. Feels sturdy. Riding at 27 mph is just fine. No problems. Front suspension is perfect for road riding. I’ve seen varying estimates from 48-56 pounds regarding it’s weight. It doesn’t feel heavy. It’s surprisingly regular-bike-like.
Back lights and brake light is a very cool feature.
It feels like the 15 tooth chainring is a mistake for a 28 mph bike. It would be perfect for a 22-24 mph bike but at 27 mph I’m just pedaling too fast. Thankfully, chainrings are cheap! I’m curious how the bike will ride with a 20 tooth chainring.
The brakes are a freakin’ dream. Just awesome. Luxurious.
The seat has gotta go and I’m planning to get seat suspension post as well. Again, these don’t seem like super-expensive adjustments.
The reason I bought this bike is because I rode a Trek Super Commuter and absolutely loved it, but I had some issues with the $5k price tag. This bike has the same Bosch system and battery, plus it has the front suspension I wanted and retails for around $1000 less. The tires are neeeearly as wide. Honestly, it feels a little better than the Super Commuter – except for the seat (still recovering). The display on the Six50 E 2 Street is way better IMHO. For some reason the Super Commuter has a smaller, less rich display. Not sure why. Both bikes have a similar sturdy feel. The Super Commuter comes with a Super Nova M99 Pure headlight that I’ve yet to compare with the one that came with the Bulls bike because the sun is still shining here – but I’m assuming the Super Nova is a bit better. The Super Commuter has a 20 tooth chainring – and I can feel the difference there for sure. But that’s a $25 adjustment.
Leandro at Propel has been good to work with. I’m really happy with my purchase. I suspect he set up the seat height for me because it was perfect as soon as I got on the bike. I would definitely consider ordering from Propel again.
That’s it for now. Great bike so far. I’m really glad did the research to find this particular model. Thanks to Court Rye for your help via email and through all your reviews.

7 years agoHi John! Awesome comment, thanks for sharing your experience buying from Propel and your thoughts on the SIX 50 E2 Street vs. Trek’s Supercommuter. Both are cool bikes but I do enjoy the suspension here and of course… saving a bit of cash. Trek has a great network of dealers and I like how their battery interfaces with the bike but in the end, it’s nice to have choice and it’s great that you’re getting support with the chainring adjustment. Consider an 18 tooth vs. 20 so you can benefit from the zippy starts and climbing with your bike AND get those slower strokes at high speed. As for weight, I use my own scale with each bike review here and found the Bulls SIX 50 to be ~55 lbs which is right in that range you shared. I always weigh with the battery and all stock accessories attached. Enjoy the ride, have fun out there and feel free to share updates!

7 years agoMy Bulls Six50 E 2 Street arrived yesterday at my home in Olympia, Washington after being shipped across the country from Propel Bikes in Brooklyn. It arrived in great shape. No dings or scrapes. I am assuming Lee, from Propel, took the time to adjust the seat to my inseam, since I had shared that information with him, and the seat position was perfect. I put the pedals on, straightened out the handle bars, charged the battery a bit, and took off riding for 16 miles.
I selected this particular bike because I wanted something that would feel solid on the street, yet could move into the mud when necessary. I live out in the country. There are lots of 50 mph roads here without shoulders. I wanted to be able to move into the dirt ditches in case of dangerous vehicles and have a good chance of staying upright. There is also a park nearby with lots of trails (nothing terribly steep) and I wanted a bike that would perform there. So far, so good. The bike feels super sturdy on trails and on the road. At 27 mph it feels unshakeable. I’m not a speed demon by any means but the 20 mph cut-off on many bikes just bugs me. It feels like I’m just getting going. 28 mph feels like a more natural cut-off point as I wouldn’t want to go much faster anyways. It also gives me the opportunity to keep up with the speed of traffic when I’m in town which feels much safer.
Early on in my selection process I tried a Trek Super Commuter and loved it, yet I was stunned by the $5000 price tag. I also wanted a front suspension. My Bulls purchase was an attempt to get something like the Super Commuter with less money, and with a front suspension. I’m not disappointed. Here’s a comparison of the two bikes:
Both bikes have that wonderful sturdy feeling, the same Bosch Performance Line system with a 500 watt hour battery, big and wide tires, fenders, and rear rack. The differences are minimal.
The Super Commuter’s tires are ever so slightly wider (about 1/8 inch maybe) but the Six50’s tires feel just as good to me.
The Bulls Six50 actually has a better display. It’s bigger with more info.
The Super Commuter has a better headlight (a Supernova M99 Pure+) but the headlight (some obscure 60 Lux headlight) on the Bulls Six50 isn’t bad at all. I’ll have to check out if I need anything more. Both bikes have a Supernova tail light but, as far as I can tell the Six50 has a better one. It’s an M99 tail light that includes 5 leds and a brake light. The Super Commuter has a 3 LED set up that does not include the brake light. I really like the brake light feature.
The Super Commuter has a 20 tooth chainring which I plan to install on my Six50, which came with a 15 tooth chainring. The 15 tooth chainring seems like a weird choice. I guess it would be better for really steep hills but in my 16 mile test ride (which I will be repeating 100s of times) I never touched the lower gears. I didn’t need them. Sometimes I just started out on the highest gear in turbo mode and I was fine. The 20 tooth chainring will run me about $25. Not a big deal. As is, the Six50 cruises easily around 23 mph. I had to really crank on it to go 27. I never got to 28 mph. I have read that adding a bigger chainring should help. We’ll see.
The Super Commuter has a carbon fiber fork versus the Six50’s Suntour suspension fork. I honestly like the suspension better for mixed trail/road use. It probably adds a couple of pounds.
The Super Commuter has 11 gears versus 10 on the Six50. Like I said, I don’t tend to use the lower gears.
The seat on the Six50 is uncomfortable. I’m going to replace it asap and probably get a seat suspension post as well. The seat on the Super Commuter was much better. I’m not sure how much a good seat costs but I imagine this upgrade along with a suspension post will be my most expensive improvements.
That’s it for my first day impressions. I want to thank Court Rye for all of his guidance via email and through this website. Also, Propel Bikes strikes me as a good outfit. I love their mission and my interactions have all been positive so far. I would definitely consider buying from them again.

7 years agoDay two – hitting the trails on the Bulls Six50 E 2 Street.
Joyful swearing. That best describes my experience. The trails that I used on my old mountain bike have taken on a whole new dimension. The drudgery I used to experience on the big hills is absolutely gone. I am easily going 15 mph up hills that used to reduce me to walking speed and unjoyful swearing because my legs hurt so bad. It’s a whole new experience. Going up big muddy hills with rocks and roots is now part of the fun. Total difference maker. I think my wife is jealous because I kept saying, “Wow, that was fantastic!”, and “Oh my God that was great!” She’s only used to hearing me say things like that in other situations where she’s more directly involved. Riding this bike on my usual trails was awesome – a paradigm shifter for sure.
Even on trails and muddy hills I’ve never touched the lowest gears. I just put it in turbo mode and zoom up. I was probably in gear 4 out of 10 on the steepest hills. Pure joy. I’m definitely getting a workout. It’s just a funner one. I just love the torque sensor on this thing. So responsive.
The brakes are a thing of beauty on the trails. Very soft and controlled. I always felt like they had my back.
It’s worth repeating how well this bike rides without power. I ended up cutting the power quite a bit on the trails because I just didn’t need it – but then when I needed it I’d kick it in. I don’t need to go fast on the trails like I do on the street when commuting. It’s a whole different game. I’d cut the motor whenever I encountered a pedestrian on the trail and slow way down.
Again, gotta get that seat addressed. That was only thing bringing me back down to earth.
Here are a few more thoughts on the Six50 E 2 Street versus the Trek Super Commuter.
* I don’t think I would’ve enjoyed the trails as much with the Super Commuter because of the stiff front fork but I could be wrong.
* I actually have a 5 led brake light/rear light/license plate light on the Six50. The Super Commuter has a three led rear light and I don’t think it has a brake light.
* I can’t tell the difference between the two bikes with how the battery works or how it’s integrated. It just clicks in really easily and I turn the key to take it out. I guess the Super Commuter has little bit more of a cradle for the battery and it’s a tiny bit more stealth. Not a difference maker for me.
Court, I’ll entertain your suggestion for an eighteen tooth chainring. That might be the sweet spot. Yeah, it would be better if Bulls had the dealer network that Trek has. I’ll see if I can convince my local shops to carry them :-)
That’s it for day two. I have a huge smile on my face.

7 years agoSome updates after a few weeks of use…
I upgraded:
I found out how much difference it makes in battery life when I stop going all-out in turbo mode. I think I went 20 miles yesterday and just barely knocked one bar (out of five) off of the battery meter. I averaged around 15 mph on mostly level trails and kept it primarily in Eco mode – with about 20 minutes in Tour and maybe 5 minutes of joy-sprinting in Turbo/Sport. This is in contrast to today’s 25 minutes of Turbo-charged hill climbing and sprinting which also took one bar off the battery meter. I probably went 6.5 miles altogether.
I’ve put 185 miles on the bike so far. I have one mechanical concern and one small annoyance. Mechanically speaking, there is a thrumming sound that started to develop yesterday at speeds over ~25 mph. I hear the sound, which is accompanied by a vibration when my right foot is on the downstroke while I’m pedaling. Once I slow down it goes away. The small annoyance is that the bike seems to top out at about ~27 mph rather than 28 mph. It cruises quite easily at between 25 and 26 mph but then I really have to work to get it to 27 mph and can only keep it there a short period. This is probably nit picky but apparently more expensive bikes such as the Trek Super Commuter and the Bulls Dail-e Grinder (that use the same performance line set up with the 500 watt hour battery back) go straight to 28 mph with less resistance. I’ve experienced this myself on the Super Commuter – and have read similar experiences on the Dail-e Grinder versus the Six50. What gives? Does the extra 1mph cost 1-2k more?
With all that said, I’m incredulous how much I’ve been riding. I’ve been mainly sedentary for a few years after suffering from chronic fatigue that seemed to come out of nowhere. This bike definitely puts me in a happy place. When I’m out riding by myself I can’t help but push it – meaning I ride hard and I break out in a sweat – probably because it’s just so fun to ride. When I ride with my wife (She has a Trek Verve+) I mellow out and go for a more sustainable pace. Either way, I’m exercising and having a blast. The fatigue symptoms seem to have dropped significantly in the last few weeks. We’ll see how I do in the coming months.

7 years agoLots of great tips and feedback there John. Thanks for taking the time to share how the Bulls SIX50 E2 has improved your health and giving some insights on how the 20 tooth chainring works vs. 15 (and that you think 18 might be the sweet spot). All great stuff, keep riding and have fun :D

6 years agoThe license plate holder is there because some European countries like Germany require pedelecs that can exceeed 45km/h to be insured and that the user be 16 years or older and helmet is mandatory. Same for scooters.

4 years agoHey Court – I’m hoping you might know if I can install 2.4″ Schwalbe Super Moto X tires on these rims without issue. The current tires are 2.25″, so there’s a slight increase with the 2.4″ set which I think should be fine but thought you might know for sure. Thanks and great review and site – we bought this bike because of your review and video! :)
ReplyCourt
4 years agoHi Quito! Cool name… I cannot confirm this, because the tight rack and fenders could be a limiting factor. Given the 2.25″ tires have knobs, if your Super Moto-X tires do not, perhaps their effective diameter is very close. This is a great question for BULLS directly. They have decent customer service with email and phone support if you reach out. If you cannot get an answer or struggle, hit me up again and I’ll ask on your behalf :)
ReplyQuito Banogon
4 years agoHey, Court – your name is cool too :)
Bulls chat support replied “Tires is tricky because BULLS hasn’t tested anything wider than what comes on the bike. I cannot assure you it will work without any issues.”
But thanks to your Forums and the help from Ravi and FlatSix911, I’ve decided to buy the Schwalbe Big Ben Plus 2″ tires because they’re as close as I can get to the Moto X 2.8″ tires that on my 2018 Lore IE. My wife really wanted those but they’re definitely too big for her E2Street. Cheers!
