This beautiful custom scooter really impressed me as soon as I saw it. As you can imagine, Steve is a experienced wooden boat builder, and he also makes fine furniture out of wood. If that wasn’t enough, Steve also owns patents for his development of the GoPed scooter “one arm” suspension. Steve made the wooden body, and the Vextrix chassis is owned by his close friend, Peter Senkowsky.
Although Steve’s creation is based on a Vectrix VX-1 “scooter”, it is a serious commuter vehicle. As a road vehicle it is rated for 68-MPH. The front tire is a tubeless 120/70 on a 14-inch wheel. The Vectrix includes hydraulic disc brakes front and rear. Although the headquarters were in Massachusetts, the Vectrix was assembled in a factory located in Poland, since Europe has remained it’s biggest market.
The powertrain is a brushless electric motor attached to the left side of the rear wheel. A thin planetary reduction brings the motor’s high RPM’s down to wheel-speeds.
The original 2006 Vectrix was delivered with a NiMh battery using 125V, and in 2008 it filed for reorganization and was purchased by the “Gold Peak Group” in China, who continued producing the VX-1, and also upgraded the battery to the LiFePO4 chemistry. In 2014, it filed for bankruptcy again and a Polish company purchased the factory. Info and pics of the original factory NiMh battery packs can be found by clicking here.
The motor is rated for 11-kW constant, and 35-kW as a temporary peak. When slowing, the throttle has a “twist-forward” position that provides regenerative braking (regen).
Here is a blog and video of a Leaf-cell pack conversion (click here) using 18 modules in a 36S configuration. This would be 130V nominal, and a peak of 148V, using the original controller, which is what I would do.
