Our take on the Kit - Fat Tad

A complete electric conversion kit built specifically for the Sun Fat-Tad CXS tadpole recumbent trike. It pairs a 750W nominal, 1000W peak geared rear hub motor in a 20-inch fat wheel with a 48V 15Ah lithium battery and an integrated controller cradle, plus a color LCD, matched wiring and trike-specific parts. The geared hub gives strong low-speed torque, which suits a heavy trike and hilly or mixed-surface riding. It is a model-specific kit rather than a universal one, so it fits the Fat-Tad cleanly but is not transferable to other trikes.

About the Kit - Fat Tad

The E-BikeKit Fat Tad Conversion System is a complete electric conversion kit made for the Sun Fat-Tad CXS tadpole recumbent trike. It includes a USA hand-built 20" fat rear motor wheel, a 48V 15Ah lithium battery, a matching 3A smart charger, a 3.5" full-color SINET™ LCD and model-specific installation parts.

The motor is a 750W nominal / 1000W peak geared hub motor. It has an internal planetary reduction and a clutch, so the wheel turns with minimal drag when motor power is not in use. The SINET™ sine-wave controller is built into the battery cradle, which reduces external components and simplifies wiring. The battery can be removed for charging or storage.

The kit is configured for the Fat-Tad CXS rear-wheel layout, fat-tire spacing, cockpit and cable routing. It has a short motor cable for compact rear routing and locking parking-brake levers with motor cutoff. You choose either a cadence sensor or a bottom bracket torque sensor for pedal assist. The cadence sensor gives assistance whenever the rider pedals. The torque sensor adjusts motor assistance in proportion to pedal force.

Questions and answers

What trike does this kit fit?
It is engineered specifically for the Sun Fat-Tad CXS tadpole recumbent trike. The short motor cable and parking-brake levers are made for that model.
Cadence or torque sensor?
Cadence sensing is the simpler option and works with the existing drivetrain. The bottom bracket torque sensor responds to pedal pressure for a more natural assist feel.
What is in the box?
The motor wheel, 48V 15Ah battery with integrated controller cradle, 3A smart charger, color LCD, Fat-Tad-specific cable and locking parking-brake levers.
How fast and how powerful is it?
The geared hub motor is rated 750W nominal and 1000W peak. Top speed depends on the trike's setup and local e-bike rules.
Can I move it to another trike later?
No. The wiring, cable length and brake parts are specific to the Fat-Tad CXS, so it is not a universal kit.

At EBK Dealers, for $1,167.00, 53% under what the other stores charge, as of our latest check.
Where can I buy the Kit - Fat Tad?
