Owner of a Virvolt 900 mounted on a 15-year-old Orléans Alma in very good condition after 1.5 years of use with a battery 36v 14'4AH I am very satisfied with my purchasing with this battery it is possible to do outings of at least 100km With an acceptable weight for riding without Assistance under good conditions I'm equipped for hiking! The only downside is that I had to go to Caen for assembly and there were no instructions for use. I recommend this electrical adapter

Top-notch electric kits that my customers love. Whether it's the 900 kit for mountain bikes or commuter bikes, or the 750 kit for road bikes, they're very reliable and the batteries are excellent quality. Fantastic.

I installed a Virvolt 900 kit. I am very satisfied with its components and the ease of installation. The motor is powerful and quiet (more efficient than other mid-drive motors).The range is very satisfactory (although it's heavily dependent on battery power and the use of the assistance feature; however, this motor seems very economical). I had a minor issue (loss of assistance) which was resolved very quickly (connection problem) by the fast and efficient customer service. Thank you to them, and best of luck and success in the adventure of reinvented mobility. Louis-Dominique.

Kit 900 installed by Gepetto in July, I've been using it extensively since September to take my children to school, sports practice… everywhere 👍😁
I use it for commuting almost every day, I've covered 3000km so far and everything works perfectly. Occasionally, the motor is a little too loud.
The 900 mid-drive motor is manufactured in France at the Renault Refactory plant in Flins. Renault operators work on the assembly line. The battery currently comes from Asia, but we are working to relocate the entire process.
