Kit - EZ-Tri Classic

This EZ-Tri Classic Conversion System transforms the Sunseeker EZ-Tri Classic delta trike into a smooth, efficient electric trike using a 500W internally geared front hub motor and an optional 48V 15Ah lithium-ion battery pack.

• Special parts and configuration designed specifically for the EZ-Tri Classic
• Top speed approximately 14 mph at 48V
• Estimated 15–45 mile range depending on terrain, rider weight, and input
• Supports both pedal-assist and throttle-on-demand

The 500–1000W geared motor features a 5:1 internal planetary reduction and a clutch mechanism for zero-drag pedaling when unassisted. Compared to direct-drive motors, it provides improved efficiency, lighter weight, strong hill-climbing torque, and a compact, stealthy appearance.

Who’s it for? Riders who want reliable, lightweight assist on the EZ-Tri Classic platform. Suitable for total system loads up to 300 lb (trike + rider + cargo).

EZ-Tri–Specific Extras:

• Pedal-assist extension cable
• Locking parking brake levers
• (2) Torque arms — both required for safe axle retention
• Battery mounting hardware as shown in photos (EZ-Tri frame is pre-tapped)

Our mission: Equip every dealer with the tools, knowledge, and support required to complete reliable, professional EZ-Tri Classic installations.

This system is engineered specifically for the Sunseeker EZ-Tri Classic delta trike.

• Front motor requires standard 100 mm fork spacing
• Optimized for stable, torque-rich delta-style handling
• Supports loads up to ~300 lb

The frame’s pre-tapped mounting point supports the included battery hardware.

The EZ-Tri Classic system installs easily using standard bike tools and the included model-specific hardware.

• Front motor wheel installs into 100 mm dropouts
• Controller, LCD, and wiring use matched connectors
• PAS sensor mounts on the crank (left-side standard)
• Parking-lock brake levers replace stock brake levers
• Both torque arms must be installed; axle nuts must be properly torqued
• Battery mounts using the frame’s factory-tapped mounting hole

Correct torque-arm installation, proper cable routing, and secure mounting are essential for long-term reliability.
