Motor & Wheel

Your choice of a front or rear wheel drive motor is laced to an e-bike rated rim by Calfee Design’s wheel building specialist. Various motor, rim, and spoke options are available to accommodate your powertrain needs.

PAS Sensor

A PAS (Pedal Assist) Sensor mounted to your frame measures crank rotation speed and direction. A magnet ring is fitted to your chainring with a custom mount designed specifically for your drivetrain.

PAS Buttons

Control buttons are neatly integrated under your shifter hoods, allowing you to adjust PAS (Pedal Assist) levels. Increase by pressing the right side button and decrease assist by pressing the left side button.

Handlebar LEDs

LED strips integrated with your bar tape display essential data while keeping the interface simple. The left side shows the current state of charge in red while the right side displays current PAS level.

VCU

The VCU (vehicle control unit) is the central computer connecting the user interface, sensors, and powertrain. It is designed, tested, and assembled at Calfee Design in California.

Motor Controller

The motor controller receives input from the Cycle Analyst computer and is responsible for smooth power delivery from the battery pack to your motor. Handles regenerative braking for applicable models.

Calfee Frame Bag

Your choice of a standard, tandem, or bar bag elegantly houses all your batteries and control electronics. Electrofit bags are fitted with an external on/off switch for convenient and quick access.

Prices range from $2500-$4000*

Every detail is managed and made to work elegantly together. On Calfee carbon frames, wiring can be internally routed and motor wires guided by expert unobtrusive frame modifications.

About the Motor, Controller and Batteries!

250 Watts to 800 Watts variable power

Power is supplied by the modular LiGo battery packs from Grin Technology. A modular battery means your system is lightweight and expandable for more assist range as needed. The number of LiGo cells selected for the system will determine the maximum power and range of the retrofit. Why pay for – and carry more than you really need?

Each LiGo pack is 2.7Ah (610g) and can be combined with additional packs to create a larger capacity battery system. In addition the LiGo battery packs are travel-ready, conforming to FAA passenger aircraft flight regulations.
