8 years agoHey Court – I love the specs on this bike except for the 20mph top speed. Is that governed by the controller or gearing? Seems like it has the motor and battery to support 28mph. If there is not an easy way to retrofit this bike to hit 28, do you have a recommendation for another commute oriented bike with this aesthetic and price range? Many thanks on your great coverage and videos on YT (of which I have watched 50+!) -Greg

8 years agoHi Greg! I’m not sure if it’s possible to overclock or change the speed on the Bulls electric bike drive system but you might have some luck getting feedback about it in the forums? I’ve read about speed dongles and different devices for the Bosch powered electric bikes. I’ll be reviewing some other Class 3 speed pedelec models soon but here’s one from Bulls that worked fairly well and offered a lot of comfort.

8 years agoAll the pictures show this bike with the saddle high. I’m not tall and want a Dutch style bike. Is this just not going to do that for me?
ReplyCourt Rye
8 years agoHi Rick! Great question… the saddle on this bike can actually go fairly low, I’d estimate that the top could be set to ~32″ from the ground because the stand over height I measured was ~29″ and of course, the saddle would add a bit to that. Now the thing is… this bike comes in four sizes apparently so it might be even lower than 32 inches! I have long legs for my height and prefer to maximize leg extension so that’s why the saddle is so high here, I always try to set the bikes up for myself before doing rides and often this shows up in the photos as well (only in this case the stock photo also shows a high saddle). So just to reiterate, yeah it can go lower and I’d actually say that this ebike has one of the lowest possible saddle heights I’ve seen for a high-step frame just given how they arranged the tubing. Hope this helps! You could contact a BULLS dealer and ask for separate measurements or even the company to get more information, hope this helps :)

8 years agoThanks for your really helpful answer. I’m comparing the Sturmvogel with the Gazelle C8 with impulse motor. I want a Dutch style upright bike. I’m not tall – 5’9″ with 30″ inside leg. Which would you recommend?! Thanks for any further thoughts. Rick
Rick
8 years agoThanks for this – it’s really helpful. I thought the impulse was rated st 70 nm and the Bosch Active at 45 andBosch performance at 60 – is that wrong? I like the Bulls partly for its look but mainly the more powerful motor and battery – but I’d need to fit suspension seat post and fenders. It’s mainly though whether for me it has the same potential set up for a sit up and beg riding style as a often have lower back problems. It’s a lot of money to spend if I get it wrong! Thanks again, Rick

8 years agoHey Rick, I believe Bosch Performance CX will get you 75nm and Brose will get you about 90nm if I’m not mistaken. We’ve really loved these bikes over at San Diego Fly Rides, very quiet and fun ride. We’ve got this model for sale now if you’re still interested! Give us a call.

7 years agoFirst off, this bike is gorgeous, we get lots of looks and comments.
The original firmware is garbage. It’s really a 16mph eBike until you get the firmware updated. If you have (off + 3 power levels), you have the old firmware. If you have (off + 4 power levels), you have the new firmware. The old firmware is so dang conservative that it cuts power way before 20mph. After the firmware update it’s like you got a new bike.
The Alfine is paired with a 22T rear cog, which is a bit too low to maintain a slow pedal cadence at 20mph. I plan on switching to an 18T and will report back the results.
Also, the brake light cable goes down the middle of the seat post, so if you replace with a suspension seat, you will have to drop the cable down the tube and lose your rear light. (the suspension seat won’t allow you to run a wire down the center as it is blocked with a huge spring and an adjustment dial).
Battery life is amazing! I’ll report back numbers when I get it dialed in with the smaller cog.
ReplyIOWNTHIS
7 years agoThe 18T cog is a hug improvement over the 22T. My wife says it feels like a new bike. Gear 1 is plenty low to get up a very steep driveway and the highest gear can get you over 25mph on a slight decline. It’s really easy to stay at 20mph continuous with the new gearing.
To perform this you will need a chain break tool like this to remove one full link (which means, take off the master link and then push out one pin, but skipping one) and an 18 tooth cog like this.
You will also need small metrics allen wrenches that are single, not as part of a tool. Here’s an example. There are some small hex screws in the drop out arm that can only be reached with a small single bent allen.
I also suggest first cleaning the chain and wrapping the tire in something protective so you don’t get grease all over. You will also need to remove the rear brake caliper.

7 years agoThis is very helpful! Thanks for sharing your experience and the outcome… along with all of the parts needed. I linked them up and changed the last one because the link wasn’t working initially. Feel free to share further in the forums if you have pictures or other tips, this really helps people :)
ReplyIOWNTHIS
7 years agoI forgot one tool…you need snap ring pliers to get the Alfine cog off the assembly. This is one of the hardest tasks in the project (adjusting the dropouts to an equal distance on both sides of the frame is the other hard task). There are several videos on youtube that show the Alfine snap-ring removal/installation process.

7 years agoHave been riding this bike for over six months now here in the U.K. The best thing about it is the battery which lasts for at least 40 miles (I’m 180 pounds) on a flat terrain and 10 miles less in a hilly terrain. One annoying thing about the bike is the rattling battery, but the worst thing is the fact that you cannot find spare parts for it here in the U.K. The supplier of this bike in the U.K. are absolutely hopeless when it comes to after sale service. So although the bike is good but I wouldn’t buy it had I known how hard it is to find replacement items. You’re better off going for a bike with more available spare parts.
I’ve tried very hard to find a spare battery but so far with no success. To replace the front light was also not easy. After much research, I found only one company in Europe which sold the same type and it wasn’t cheap. So in conclusion, the bike is good but I’d think twice before buying it again due to extremely poor after sale.
ReplyCourt Rye
7 years agoAww, that’s a bummer. Thanks for sharing how the bike has been good (along with some stats about range and your weight) and how you think it could be improved (better service in the UK). I know the team working for Bulls here in the US and they seem to be much more responsive, I wish that were the case for you too… it hurts the global brand if one region is dropping the ball :/
ReplyM AFREN
7 years agoAlso, if you, like me, like to ride off road, lack of suspension is a big problem with this bike. I’ve installed body float seat suspension but it is the lack of front suspension that lets this bike down.
M AFREN
7 years agoEver since buying this bike over six months ago, one question which I constantly get asked is about the range. This is a very difficult to address, for the answer very much depends on the age of the battery, the weight of the rider including additional accessories mounted on the bike, the terrain, wind, etc.
I now believe that I can answer the question of range with some certainty but first the stats. I’m about 83 kg (183 lb) and I have loads of accessories on my bike ranging from a rack, pannier bags normally full of stuff such as spare tubes, repairing kits and tools, towel, front and rear lights, bell, mud guards (both back and front), my cell phone holder, etc. These additional items weigh approx. 15 kg (33 lb), so a total weight of 98 kg (216 lb).
So what range have I achieved bearing in mind the above stats? The terrain I cycle on almost a daily basis is definately not flat. It has many hills some measuring up to 800 meters (over 2,600 ft) but obviously a lot of downhills too. Here is a link to my route. With all of the above in mind, below is the range I have managed to achieve on my 6 month old battery:
I hope this helps those who have been wondering about the range of the battery on Bulls Sturmvogel E Evo.
ReplyCourt Rye
7 years agoThis is fantastic, thank you so much for the detailed feedback on range for your Bulls electric bike! I am sure this will help people out and it’s also neat for me to see because I weigh ~135 lbs and rarely bring gear or accessories when filming reviews. It’s amazing how far you can go on a charge, these new e-bikes with higher capacity Lithium-ion batteries do very well.

6 years agoI have now owned this bike for almost two years and have ridden it for just under 10,000 miles. I have had to replace the motor once during this time because of excessive noise, the crank arms over three times (the non-drive side), the front tire 3 times having had over 10 punctures and ultimately forcing me to replace them with much better tires. Now, the big question: would I buy the bike again? The simple answer has to be, no. The biggest problem is lack of any suspensions. Even though I have installed one for the seat but it’s very uncomfortable on long rides. Also, very difficult to find spare parts. Furthermore, 26″ wheels are, in my opinion and in the opinion of many professionals, is the wrong size wheels. Finally, I live and bought the bike here in the U.K. which has meant the after sale service is absolutely horrible.
ReplyCourt
6 years agoHmm, thanks for the honest feedback here, sorry you had to get the motor replaced. I hope it holds up alright for you and I welcome further input on this or other models you get someday :)

5 years agoHi, I recently replaced the rear sprocket on my Bulls Sturmvogel E Evo 2016 model which is equipped with a Shimano Nexus 8 speed Internal Gear Hub. In doing so, I may have replaced it with a sprocket having a different number of teeth, resulting in a slower bike. Unfortunately, I disposed of the old sprocket before realizing the reduction in speed. Would anyone with a similar bike and configuration please. tell me the size of the rear sprocket? Thank you.
ReplyCourt
5 years agoHi! I cannot say for sure, but I think the rear sprocket is 24 tooth. I’ve looked closely at the photographs here and done my best to count. I’m sorry that this information was not measured during the review, as it is something I usually record. The chainring has 44 teeth. Hope this helps!
