Store Under Maintenance, Apr 2nd - 12th 

Grin's storefront will be disabled until Monday while we rollout and test a number of system changes, and also catch up processing and shipping all the backlogged orders we have in the queue.  You should still be able to add items to your cart and have them ready to checkout when we re-enable the store on the 12th.  See our blog post for more details.

The Bafang G311 front geared motor kits are ideal for those who want a small and lightweight geared motor in the lower power 250-500 watt range. They require a fork with slotted dropouts and fender eyelets to use our included torque arm.
