Grintech E-bike Conversion Kit for Folding Bicycles and Bromptons - kit does not include battery
Grintech has made an electric bicycle conversion kit customised for use on Brompton folding bicycles with minimal effect on the unique and all important Brompton fold. The motor has been re-designed to fit into the 80mm front fork drop outs without any need to stretch the forks out (until now this has been a common issue on folding bike conversion kits), so the motor drops neatly into the Brompton without modifying the original bike.
The controller comes with a custom designed plate to mount onto the front mudguard. There is a number of options for pedal assist or throttle or both and it is also compatible with Grintech's cycle analyst.
The only thing that has not yet been designed specifically with the Brompton in mind is the battery, leaving the consumer the option to use any battery with an anderson cord output.
Please note that this is not an official Brompton product. Brompton has been working on an electric conversion kit for many years now and intend to release one in the future. They do not endorse any third-party conversion kits and the warranty of your Brompton may be voided by retrofitting an electric conversion kit to it.
You can see more information about this conversion kit on Grintech's page.
The prices listed consist of either the NSM or SAW motor, 20amp controller, eZee battery display, throttle and the hardware to install the conversion kit
Hints of the game:
- You'll need a Brompton bag for the battery
- Purchase the fender to minimise water damage to the controller
- Purchase the rear rack to increase luggage capacity - the battery may be taking up more room than expected in the front bag
- Splash out and put some new comfortable grips on that beautiful conversion
- Upgrade your tyres to avoid flats
You'll need to purchase a battery with this conversion kit. Our recommendation is the eZee 36V 15Ah Flat Pack battery, stored in a Brompton front bag.
