Overview
An adult electric fat-tire bike sold in F6, F6S, and F6Pro configurations with different motor and battery combinations, NFC or passcode unlocking, hydraulic front and rear suspension, and 20x4 inch tires for pavement, sand, or dirt.
DTTZH's own listing gives conflicting wattage and speed figures across the three trims, so treat exact power and top speed as variable by which configuration ships rather than one fixed number. What is consistent: a removable 48V battery pack, a 3A fast charger that cuts charge time versus the standard 2A charger, and three ride modes (throttle-only, pedal-assist, and manual) paired with a 7-speed drivetrain.
- NFC card or 4-digit passcode unlock
- Removable 48V battery with 3A fast charger
- 20x4 inch fat tires, hydraulic suspension
- 3 ride modes with 7-speed shifter
Who it's for
Riders wanting a heavy-duty electric fat bike for commuting or trail riding, including parents buying for teenagers who want speed and range.
Pros and cons
- Hydraulic front and rear suspension for rough terrain
- NFC and passcode unlock, no keys needed
- Customer service replaced failed motors and screens
- Arrives about 95 percent pre-assembled
- Speedometer and mileage reportedly read low
