Parting Out My Grin Technologies Dahon Build

Post by dlhinkley » Oct 15 2016 5:34pm

I'm parting out my custom build of my Dahon Mariner using parts from Grin Technologies (shown below). I've already sold the bike, now I need to sell the parts (motor, controller, battery, brakes). The build worked out real well and ended up only riding for about 100 miles. The build worked great on flat ground and small hills. The only Dahon specific part is the motor. The remaining parts should work any model of bike.

Each item will sell for the price listed plus shipping in the United States. Payment will be by PayPal.

If you don't want to ship outside the US, I'd like the controller.
