Overview
A 2000W peak dual-suspension electric dirt bike with a 48V removable battery available in 20Ah, 35Ah or 60Ah capacities and a claimed 28 mph top speed. Aimed at riders who want an off-road styled ebike for trails and rough terrain.
Deepower pitches this as an electric motorcycle-style ride with a 30 degree climb rating and up to 100 miles in pedal-assist mode on the largest battery, though real-world reviews show top speed varies noticeably between units. The bike also ships with a software speed limiter that the manufacturer's own instructions describe disconnecting to unlock full performance.
- 2000W peak motor, 30 degree climb rating
- 48V battery in 20Ah, 35Ah or 60Ah
- 20x4 inch fat tires with dual suspension
- 7-speed drivetrain, dual disc brakes
Who it's for
Suits riders who want an aggressive-looking fat tire ebike for trails and hills and who don't mind adjusting settings after delivery. Less suited to buyers who need the advertised top speed guaranteed out of the box.
What buyers say
From Amazon customer reviews.
Reviewers describe the bike as sturdy and comfortable to ride, but several report the real top speed falling well short of the advertised 28 mph, one even after following the disconnect procedure for the speed limiter, and one buyer received bent battery pins that limited output to 15 mph.
Strengths and trade-offs
Drawn from this product's published specifications.
- Dual suspension smooths rough trail riding
- Multiple battery capacities for longer range
- Dual disc brakes for reliable stopping power
- Reported top speed varies widely between units
- One buyer received bent battery pins
- Better suited to lighter riders per feedback

Questions about the Deepower QS7
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
What is the QS7's actual top speed?
Deepower advertises 28 mph, but buyer reports range from around 15 mph to close to 30 mph depending on the unit and whether the speed limiter was disconnected.
How far can it go on a charge?
Up to 70 miles in pure electric mode and up to 100 miles in pedal-assist mode with the 60Ah battery, per the manufacturer's specifications.
Is it suited to larger riders?
One buyer over 270 lbs found the bike underpowered and slower for their size, while a smaller teenage rider found performance closer to expectations.
