buuuut... reducing the crank length by 5mm and adding 3mm (?) of nylon is not that of a big gain. I would definitely opt for shorter cranks, they totally make sense on an e-bike. And don't care about scratches too much. Sooner or later you will have adopted your riding-over-obstacles style and terrain reading skills so you don't strike your pedals anymore. We've all been there
You're right to be concerned, pedal strike on my Jam2 last Thursday resulted in powerloss and a hard pedal home.I'm more worried about damage to the motor than I am about the battlescars!
All that force goes straight into the crank tube & motor mechanism?
No, you misunderstand. It was not Di2 gearing, my bike has standard gearing.Yet another case of Di being useless on a mountain bike
Yup, most people on EMTB's haven't a clue about mountain biking & avoiding obstacles in general, obvs most people on this forum do but its not the norm.I asked a mate of mine about this topic. He has been riding emtbs for much longer than me and he ventured a theory that people with emtbs get used to pedalling all the time, even around bends and consequently have more pedal strikes. It's a theory that would explain the incidents, but is it likely? Or are we both missing something? Are riders riding into more technical and rocky terrain simply because they are on an emtb?
Most ebikes have a wider q factor than conventional bikes so we're catching objects to the side of the traditional riding line ?Or are we both missing something? Are riders riding into more technical and rocky terrain simply because they are on an emtb?
It's already happening. I've tested a Ghost eBike last year and instantly asked the shop guy if these are shorter crank arms, cause they felt different to me. Yes he said, 155mm crank arm length as stock.Would be surprised if the emtb brands dont go shorter on stock arms very soon.
No I have never measured the Q factor on any bike, but thanks for giving me the answer as it will save me the bother.Steve
I'm sure you already know this, apologies if you have already mentioned it, but the Q factor on your Focus and all Shimano Steps bikes is the same as non e-bikes.
And regarding pedal strikes, surely they are directly related to the type of terrain you ride.
I have never had a pedal strike on a fire road, a trail centre track nor little woodland single tracks, but I can take you on routes where even the best can get caught out.
