Overview
A 48V 12Ah removable battery and a motor rated 750W sustained, 1500W peak, power the Askgo F28, a 26 inch tire electric mountain bike aimed at hilly daily commutes.
Askgo is upfront that the 1500W figure is short-term peak output and the sustained rating is 750W, a more transparent way to label the motor than listings that only quote peak numbers. The frame is rated to 350 lbs and fits riders from 5'1" to 6'6", and the bike ships 95 percent pre assembled.
- 1500W peak / 750W sustained motor
- 48V 12Ah removable battery, 4-5 hour charge
- Fits riders 5'1" to 6'6", up to 350 lbs
- 7-speed gearing with 5 pedal assist levels
Who it's for
Good for commuters and weekend riders who want clear torque on hills and a wide rider size range. Less suited to riders wanting sustained power beyond 750W or a very lightweight bike, since it weighs about 50.7 lbs.
What buyers say
From Amazon customer reviews.
Both early reviewers focus on hill performance, describing the motor as having plenty of torque for a hilly area and the frame as sturdy with clean welds for daily commuting.

Performance notes
Peak output is 1500W for short bursts and 750W sustained, enough per the listing to handle 30 degree grades, with the 48V 12Ah battery charging fully in 4 to 5 hours and giving a claimed range up to 65 miles. Dual disc brakes and front fork suspension handle stopping and rough roads, and the drivetrain adds 7 speeds plus 5 pedal assist levels along with throttle, cruise, pedal only and walk assist modes.
