The max battery kit works well with my full suspension MTB , off road or a more leisurely on road ride. Nice and lightweight and doesn’t get disturbed or rattled by heavy landings (“casing” dislodged the peddle sensor a couple of times but nothing major that couldn’t be adjusted). Have to use the cable ties on the crank as not enough room due to the rear suspension link. The articulation of the joint for the crank fixing needs to be a bit more flexible as that took me the longest thing to set up to maintain a perfect 3mm gap all the way round. I did mange it and used that metal weld paste to hold it securely in place.
