Kit - Eco-Tad

This Eco-Tad–specific E-BikeKit system converts the Sunseeker Eco-Tad SX tadpole trike into a lightweight, fast, and efficient electric trike using a 500W internally geared rear hub motor and a 48V 15Ah lithium-ion battery pack.

• Special configuration tailored for the Eco-Tad SX
• Top speed up to approximately 26 mph
• Estimated 15–45 mile range depending on rider, terrain, and input
• Supports pedal-assist and throttle-on-demand

The 500–1000W geared motor uses a 5:1 planetary reduction and internal clutch for zero-drag pedaling, higher efficiency, strong hill-climbing torque, and a stealthy, compact motor profile compared to similar direct-drive motors.

Who’s it for? Riders looking for premium performance, low weight, and efficiency on the Eco-Tad platform. Recommended for total loads up to 300 lb (trike + rider + cargo).

This system is designed specifically for the Sunseeker Eco-Tad SX tadpole recumbent trike.

• Fits rear dropout spacing of 135 mm
• Optimized for torque-rich tadpole trike handling

Some trikes may require minor adjustments depending on frame condition or previous modifications.

The Eco-Tad system installs using common bike tools and includes all required hardware for most stock frames.

• Motor wheel installs directly into the 135 mm rear dropout
• Controller, LCD, and wiring use matched connectors for simple installation
• PAS sensor mounts on the crank (left-side standard)
• Use locking parking-brake levers supplied with the system
• Torque arms must be installed and axle nuts properly torqued
• Battery must be securely mounted using appropriate hardware

Proper torque-arm installation, cable routing, and secure mounting of all components are essential for safe, long-term use.
