ENVO Flex Trike – Fat-Tire Electric Adult Trike for Stability & Cargo
The ENVO Flex Trike is a versatile, folding electric tricycle designed for adults who want maximum stability, cargo capacity, and long-distance range. Built on a durable step-through frame with fat tires and a smart powertrain, it’s perfect for commuting, running errands, or exploring off-road paths — all while carrying heavy loads with ease.
Reliable 500W Motor & Rear Differential
The trike features a geared rear-hub motor rated at 500W, delivering smooth, efficient power with up to ~80 Nm of torque. A unique rear differential powers both back wheels, ensuring traction, balance, and confident handling even on uneven surfaces.
Impressive Range with Dual Battery Option
Standard setup includes a 48V 15Ah battery for solid range, while an optional second 48V 17.5Ah battery nearly doubles your reach — allowing for up to ~220 km (~135 miles) on lower assist levels.
Strong, Folding Frame
Constructed from hydro-formed aluminum, the Flex Trike’s foldable, step-through frame supports up to 400 lbs (180 kg), offering stability and ease of mount/dismount while being compact for storage or transport.
Comfort & Traction from Fat Tires & Suspension
- 20″ × 3.0″ fat tires for grip and cushioning on multiple surfaces
- Lockable suspension fork with 80 mm of travel helps absorb bumps and rough terrain
- Wide, cushioned saddle built for long rides and heavy loads
Smooth Pedal Assist System + Thumb Throttle
A torque-emulating pedal-assist sensor provides 5 levels of smooth support, while a thumb throttle gives you instant power boost — ideal for starting from a stop or climbing hills.
Powerful Braking & Safety Features
Hydraulic disc brakes (on all three wheels) give reliable stopping power. A built-in motor cutoff ensures safety during rapid deceleration. The trike also includes bright LED lighting with a front headlight and brake-activated rear light for visibility.
Smart Load-Carrying & Utility Design
- Generous rear cargo basket rated to carry up to 150 lbs — great for groceries, deliveries, or gear
