The Z20 is a fat tire e-bike built around a 750W motor and a 17Ah battery using LG 18650 cells. Those 26 by 4 inch tyres are the point: they float over sand, snow, gravel, and broken trail where a normal bike sinks or slips. An aluminium 6061 frame keeps the weight to 61.7 lbs, dual oil disc brakes handle stopping at both ends, and it carries up to 330 lbs. For the US market the top speed is set to 20 mph.

Product Highlights
Fat Tyres Change Where You Can Ride
At 26 by 4 inches, these tyres spread the bike's weight across a much larger contact patch. Soft sand, fresh snow, and loose gravel become rideable rather than a walk.
LG Cells Inside
The 17Ah pack is built from LG 18650 cells, a known quantity in lithium batteries, and charges in 3 to 5 hours.
Aluminium 6061 Frame
A 6061 aluminium alloy frame keeps a fat tire bike down to 61.7 lbs, which matters every time you lift it onto a rack.
Oil Disc Brakes
Dual oil disc brakes front and rear give the consistent stopping power a heavy fat tire bike needs, wet or dry.
Carries a Real Load
A 330 lb maximum load leaves room for a larger rider plus gear on the sort of trips fat tire bikes get used for.
Set for US Rules
The top speed is set to 20 mph for the United States, which keeps it within the usual e-bike classification rather than pushing it into moped territory.

- Wear a properly fitted helmet, and use lights and reflective clothing in low light.
- Only one frame size is offered, 48 cm, suited to riders roughly 165-170 cm tall. Check your height before ordering.
- Do not exceed the 330 lb maximum load, and allow longer braking distances when loaded or riding downhill.
- Charge with the supplied charger only, away from flammable materials, and do not leave it charging unattended overnight.
- Store and charge the battery within the temperature range in the manual, and stop using it if it is damaged, swollen, or behaving unusually.
- Fat tyres run at lower pressures than standard tyres. Check pressure regularly and follow the pressure range in the manual.
- Have the bike assembled and safety checked by a qualified mechanic before first use, and check brakes and fasteners before every ride.
