While it was agile and quicker handling, the Specialized Turbo Levo Comp lost ground in this rating metric due to the somewhat abrupt pedal assist cutoff that occurred the moment you stop pedaling. This abrupt power cutoff caused awkward moves in slower technical uphill sections when jockeying pedals to avoid rock strikes. The Bulls E-Stream had power for days and could mash its way up just about anything, but its overall weight and size made it a little more awkward in slower or more technical sections of climbing. The Trek Powerfly had a long wheelbase, reach, and chainstay length, giving the bike a long rear end that kept impressive traction while climbing as long as you kept your momentum, the overall length of the bike, however, made it a little tougher to negotiate in the tighter stuff.
Certainly very excited about this e-MTB. Bulls has decided to make use of the super powerful Shimano Steps E8000 motor. With a 500 wH battery and a 250 watt motor, this bike will assist you up incredibly steep hills but not burn too much of the battery. Bulls also sets this bike apart by setting it up with Shimano Di2 electronic shifting and a Deore XT drivetrain for precise and quick shifting. The other specs are about what you’d expect from a ride in this price range. Magura MT5 hydraulic disc brakes, RockShox suspension with 150mm of travel, and Rocket Ron tires on tubeless ready rims let you take on any mountain trails.
250-WH of Hobby King LiPo, $3,000 spent in parts with a carbon frame (It would be $1,000 cheaper and only 2 pounds heavier with an aluminum frame). This bike was home-built by Kepler who decided to sell his modified 50mph Stealth Bomber and build this bike with the funds. Read our article on the Super Commuter and Keplers decision to go with a lightweight ebike.
Using that same meticulousness, he built a mountain bike out of titanium in 1995, and it is the lightest in the world. It weighs only 5.855 kg (12.9 lbs), and it became his second “Guinness Book” entry. His latest entry into the record-books came in 1998: only 9.74 kg (21.4 lbs) for the lightest electric bike, of course using his custom titanium frame. The power was from an electric friction-drive similar to the Solex moped, powering the rear tire, but…that drive system would prove to be unacceptable for an off-road mountain bike.
