Kit - EZ-Tad

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

• Purpose-built configuration for the Sunseeker EZ-Tad SX
• Top speed up to approximately 26 mph
• Estimated 15–45 mile range depending on rider, terrain, and riding style
• Supports pedal-assist and throttle-on-demand

The 500–1000W internally geared motor uses a 5:1 planetary drive paired with a clutch for zero-drag pedaling when unpowered. It delivers excellent efficiency, strong climbing torque, quicker response, and a smaller/lighter profile than equivalent direct-drive systems.

Who’s it for? Riders who want top-end performance, lightweight efficiency, and excellent torque delivery on the EZ-Tad chassis. Recommended for total system loads up to 300 lb (trike + rider + cargo).

Our mission: Give every dealer the confidence, clarity, and support needed to deliver a clean, professional EZ-Tad installation.

This conversion system is engineered specifically for the Sunseeker EZ-Tad SX recumbent tadpole trike.

• Fits standard 135 mm rear dropout spacing
• Optimized for tadpole-style stability and handling
• Supports total loads up to ~300 lb

Minor adjustments may be required depending on frame age or configuration.

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

• Motor wheel installs directly into the 135 mm rear dropouts
• Controller, LCD display, and cabling use plug-matched connectors
• PAS sensor mounts on the crank (left side standard)
• Locking parking-brake levers replace stock brake levers
• Torque arms must be installed and axle nuts torqued properly
• Battery must be securely mounted using appropriate hardware

Proper torque-arm installation, correct cable routing, and securely mounted components are essential for safe and reliable operation.
