These are replacement ISIS Cranks Arms in Black for use with Bosch eBike systems. They come as a pair (Left and Right Crank Arms) and fit straight onto all Bosch eBike years.
Length: 175mm
To replace the crank arms you will require a crank puller and an allen key, available from our store.
These cranks are ISIS fit for Bosch Performance, Performance CX and older type Active Line. They will not fit the 2018+ Active Line / Active Line Plus motor which uses the smaller Bosch BNI Interface.
These cranks will not fit certain 27.5+ or fat bike models, some PLUS bikes have a special offset ring and longer crank body.
We list the 27.5+ cranks here that use an offset. Or the fat bike cranks here.
