    Anyone know how easy/difficult it is to obtain a replacement key for removing the bosch battery from my Cube Race ebike?

I went from the standard 12T chainring to a 15T to get a bit more top end speed, and fitted a new chain of the same size at...

I've started hanging my ebike from the garage roof but its a heavy...

    Park Tool CM5.2 Cyclone Chain Scrubber

    Anyone got one of these? Im wanting to get one but the Youtube videos tell you to fit it and rotate the pedals backwards for the chain to pass through it.
