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.
On the 8.0 specifically, Haibike sets you up with the brand new Yamaha PW-X motor. This motor comes standard with a 500 watt hour battery, Bluetooth connectivity, and 80 nm of torque out the gate. The PW-X also boasts the benefit of a dual chainring up front. This means you’ll save some battery if you’re willing to work a little harder and use those gears! Speaking of gears, you’ll get a Shimano Deore XT drivetrain. Pair that with Fox 34 Float Performance front suspension and a Fox Float DPS rear shock (150mm travel) and you’ve got a fully-capable, all-around ride.
R&M also provides only top-of-the-line components. You’ll get a Shimano Deore XT Shadow+ 11-speed drivetrain, Shimano Deore XT brakes, and a Fox Float 34 Performance Boost suspension fork with 120mm of travel. You can even upgrade to a 14-speed Rohloff drivetrain. If you’re using it for camping, you can include a rear rack to carry up to 60 pounds of gear along with you. 

A: Electric bikes are designed with compact electric motors which are usually attached to the back of the front wheel and housed in a hub. There are a number of controls with a user interface which is where all the motor operation is done by the rider. Here one can control the speed, braking and other things such as battery management. Some e-bikes have other electric components such as a sensor which also help in geometry and stabilization.
With an electric mountain bike (or e-MTB) that gives you assistance up to 25kph, it’s possible to pack twice as much riding into the same amount of time. Those five great trails that you normally ride after work can now be ridden twice. That boring singletrack climb on your lunchtime loop suddenly becomes the highlight of your day. With the extra push from the motor it’s easy to double the distance covered, or do the same ride in half the time.
