INDUSTRIAL DRIVE SYSTEM – Commercial Electric Bikes

Ideal for Pedicabs and Cargo bike applications (commercial electric bikes), this two-stage commercial drive system carries the trademark Davinci high efficiency architecture geared for heavier applications with lower overall speed. All drives are weather resistant and can be fan cooled, the system layout and offset can be easily reconfigured to accommodate many different chassis designs & configurations.

Unique sleeve motor mounting system.

Torque limiting is important for high power electric systems. The torque limiter protects the drive line and the electronic motor controller from overloading due to a number of factors. It also improves acceleration by reducing wheelie or wheel-spin tendency. The torque limiter can be easily adjusted or “Tuned” for each specific application to provide more or less limiting (slip). We pioneered the use of torque

The motor slides through a “Cradle” (or sleeve) that wraps around the motor and pressure clamps to the can. The Cradle, then, mounts in a Carriage supported by 1.5 inch wide aluminum arms. This system eliminates any flex in the reduction system allowing far higher belt tension and wider belts. This is critical for high power systems, such as running a 3215 or, more critically, the big 9,000 watt 3220 motor. It also pulls heat from the motor can and transfers that heat directly into the reduction system framework. The framework has far higher thermal mass and surface area than the motor by itself. This drops motor heat tremendously! Normally these motors do not run very hot. However, under hard running, heat can build up. This drive system solves this heat buildup in a very innovative way.

Adjustable carriage to mount base position.

Torque limiting is important for all high power electric systems. The torque limiter protects the drive line and the electronic motor controller from overloading due to a number of factors. It also improves acceleration by reducing wheelie or wheel-spin tendency. The torque limiter can be easily adjusted or “Tuned” for each specific application to provide more or less limiting (slip). We pioneered the use of torque limiters on these systems years ago and have refined the system to be truly reliable, easy to adjust, and inexpensive to service if ever needed. The industrial drive system uses a steel torque limiter.
