8 years agoHi Court! Just curious how much effort is it to pedal this and other similar weight FS MTB e-bikes at or above the 20 mph motor assist cut-off point? In other words, do you need “pro cyclist legs” to reach and maintain higher speeds (i.e., say 21 to 25 mph) on flat paved surfaces with no head wind pedaling in the highest gear (for this bike = 3.5 gear ratio) assuming pedaling at a high cadence (above 100-120 RPM)?

8 years agoHi Pete, in my experience it is very difficult to top and consistently maintain even 20 mph on flats with calm air if the motor is not supporting you. The added weight and friction of electric mountain bikes is a limiter. There are some eMountain bikes that have Class 3 drive systems which can hit ~28 mph but they are rare. This is just my experience and I haven’t focused on it as much as I should… I’d love to hear your experience if you can get out and test the theory. I regularly top 20 mph but it’s usually on downhill sections.

7 years agoI got this bike – E-Stream EVO 2 (hardtail). Here’s the good, the bad and the ugly.
The good: The bike is heavy, no doubt. Without assist, this moves like pulling a boat away from the dock with a rope in your teeth. Turn on the assist though and this bike is NIMBLE – moves like a dream! I love the fact that this has a huge 650 watt-hours battery, one of the largest I’ve seen. At level three assist, (4 is the max) in hilly territory, I am able to get 15 miles out of each bar. With 5 bars, this should get me 75 miles. Of course, I don’t like to shave it that close. As I mentioned, if I ever run out of juice it’ll be like towing a boat overland. But I’ve gone on a number of 45 mile runs and come back to base with two bars of juice left on the battery. The motor is silent and lends such a natural and smooth assist to your own effort. This bike makes biking fun again!!!
Here’s the bad and the ugly. HUGE design flaw, embedding the battery in the *bottom* of the downtube. Just this past Monday I locked in the battery and set off on a ride. I didn’t get far when I hit a bump at 20mph and CRASH, the battery just dropped out of position. Now the battery is dead and it’s my word against the dealer. I say I locked the battery in place, the dealer says no – user error. Not sure where this is going to go, but these batteries are $950. Not too happy right now…
Suggestion for manufacturer:
Once I get back on the road, I am going to use a couple of velcro straps to augment the locking mechanism to make sure that, if the battery drops out of place, at least it won’t smash against the pavement.

7 years agoOuch! Thanks for tactfully sharing your difficult situation Yossi, that sucks. I didn’t drop any batteries during my tests but I did feel that the interface was overly complex. You have that slider lever and a keyed locking core… I noticed that I did not have to lock the key in order to mate the battery, and this would let people potentially just unlock and take the battery (or maybe allow it to clunk out easier as in your situation). The charging port cover is also a bit finicky. Definitely room for improvement… but it looks like Bosch is also going for the under-mount approach with their upcoming Powertube design. For me, it’s difficult to bend down and pull the battery out this way vs. lifting up. So yeah, I like how Specialized did it with their Turbo Vado which also uses a Brose drive system. I guess Brose allows each manufacturer to set their battery up however they want.

7 years agoIn all fairness, I should mention that the question of warrantee isn’t entirely up to the dealer. The dealer is a nice guy, and he’s trying to work it out but given the fact that the case is a bit banged up, he doesn’t feel that there is any chance of getting the manufacturer to honor the warrantee. That being said, the dealer is trying to work with me, to revive this battery, either with assistance from the manufacturer, perhaps they’ll recondition the battery for me for a fee, or as a last resort, perhaps we’ll open the case ourselves and hopefully find some loose connection which can be easily fixed. If anyone wants a good dealer in the Hudson Valley area I could name him, but I don’t know if you allow that level of blatant commercial ‘advertising’ on this forum?
Anyway, the hit to the battery stings, but I am having tons of fun on this bike. (I am mobile again because I had already ordered a spare so that I can do centuries.) I would encourage Bulls to tighten up the engineering of the locking mechanism to prevent activation unless the battery is firmly locked into place. This would be a low-tech mechanical solution with a huge bang for the buck for consumers.

7 years agoJust a follow-up to say that I’m getting ‘radio silence’ from both the dealer and the manufacturer on the question of whether I can get the battery replaced under warrantee or at least repaired. It was all smiles when I was shelling out the $4,500 for the bike and the extra battery but where’s the support???
Disappointed.
ReplyCourt Rye
7 years agoHmm, that’s a bummer Yossi, maybe Bulls will reply or be more available to help now that Eurobike and Interbike have ended. Try reaching out again, some dealers even go to these events and can get distracted. I just got back myself and have been behind on emails
