Mounting kit for second Hailong battery for 50 Rebels e-bike

Rayvolt Ringo - The Street Cowboy Off-Road yet Urban. Compact but generous. Vintage yet modern. Ringo is a stylish post-apocalyptic looking compact bike, made for the city and the road with an all terrain versatility. This practical two-seater bike has a head-spinner look, that will let you be the eye-catcher of the road, while riding with someone on the back. This bike combines a great look, a comfortable position, and the features of all the latest Rayvolt smart technology. Ringo has an intelligent regenerative brake system. The electronic braking system, fitted into the brake levers, sends a data signal to the motor controller that provokes a reverse effect in the motor. This converts torque into resistance using the wheel inertia to generate electricity and recharge the batteries.   In simple words, the regenerative braking acts like an ultra powerful dynamo when the levers are pulled.   The Eiva2.0® is a Rayvolt's developed software to control, customize and monitor your Rayvolt bike. An Eiva® computer can be purchased and secured mounted to the handlebars, ready to go whenever you are. The software can also be downloaded for use on an existing Android or iPhone.
