Bosch’s flagship mountain bike system uses a mini drive ring with internal gearing to send its power to the drivetrain. There’s some resistance in the system over 25km/h, but when you first press down on the pedals there’s an impressive surge of power, and it offers good support over a wide cadence range. Its size has an impact on the width of the cranks (the Q-factor) as well as the chainstay length of the frame, and it’s not the lightest system on the market at 4kg for the motor. On the other hand, Bosch is the most established player on the market, and its system has proven itself over many years.
Meter with 3-speed smart buttons: The speed button helps you to choose how first you want to go. The bike is by default at ‘’low’’ level. To increase the peddle assist level, press the ‘’+’’ and you will switch from low, to mid or high. “High” is the maximum level that will provide fast speed while pedaling, and to decrease speed level you need to press the ‘’-” button. The ’-” can also be used to eliminate the three pedal assist levels and switch into pure E-bike where you are only required twist the throttle as you cruise all the way.
What i’d really like is the ability to custom tune the standard speed settings with regard to the torque curve/output and perhaps have a top speed of 18mph or thereabouts, back when i could ride a normal bike under my own steam there were some sections of my local trails where i could easily maintain 20mph+ through the single track (allowing for acceleration out of the corners) as it was on a slight fall line. It’s all brain-farts at the moment so the tuning kit is still in my toolbox and it may stay in there.
yep ..they’re fantastic …one of my best ever buys … stopped biking 3 yrs ago due to suddenly developing pain in both knees ..diagnosed as arthritis . recently bought an ebike to try and make a comeback and believe it or not i’ve lost 10kg and knees are getting better all the time so much so i normally only use the lowest assist setting . Try one ..it’ll put a smile on your face guaranteed!
My first instinct is that it's a horrible idea. We're cyclists because we are fit enough. We've earned our way to the top. Why should some couch surfer be able to meet me there to enjoy the downhill? (I'd beat him down of course because my bike is lighter and more nimble.) And also, where do you draw the line between an electric bike and an electric motorcycle? I'd hate to meet a Zero FX or MX coming up the downhill trail I'm riding.
