This, of course, is good news for Commencal customers with EP8 drive units and e*thirteen cranks, and were hopeful other brands will follow suit. They could have gone "yeah the rattling sucks but we hope you appreciate the motor nonetheless" but instead they composed this pure poetry.

So then it gets really confusing as it seems like the first bar lasts 30% and the last one 10%. There are a lot of factors that influence range including rider weight, tyre choice, trail conditions, and elevation. Along with the new EP8 motor, Shimano has also released a larger 630Wh battery, which seems to be the most popular option at the moment youll find it inside both the Canyon Spectral:ON and Merida eOne-Sixty.

This is part of our COMMENCAL Care program, we consider a warranty case should have no cost at all for any of our customers..
