This is the replacement left brake lever for your Flash. This fits on the left side of your handlebar. The red 2 pin connector is included on this lever. You will need a 5 mm wrench orallen key (not included) to replace your brake lever.
I had reached out to Flash about an issue that I was experiencing and they went above and beyond to fix it. The gave me amazing advice, guided me on what I needed to do, helped me selecting the parts I needed and even included and extra part I needed to fix something else that I didn’t know but they identified in the photo I submitted. I’ve been with the company as one of the first backers of the Flash V1 and I would recommend Flash to everyone based on the quality of product and their amazing customer service. This is the model of how all businesses should treat their customers.
