Biktrix Stunner Step-Over Auto vs Velotric Discover M
Two commuter e-bikes at a similar price, compared on the same normalized specs. Both scored by us, both reviewed in full.
The verdict
They score identically on Genius, so this comes down to whether you value torque and battery capacity (Stunner) or lighter weight, gearing, and payload headroom (Discover M) more than the $150 price gap.
Buy the Biktrix Stunner Step-Over Auto
Buy the Stunner Step-Over Auto if you want the most torque for hills or loaded starts, a bigger battery, and don't want to think about shifting since it runs an automatic 3-speed hub — plus it's $150 cheaper.
Buy the Velotric Discover M
Buy the Discover M if you'd rather carry less bike (16 lb lighter), want a real 9-speed drivetrain for varied terrain, need the higher 440 lb payload capacity, or want the longer claimed range even though both numbers are optimistic.

- Biktrix Stunner Step-Over Auto costs $150 less.

The short version on each
Biktrix Stunner Step-Over Auto
What's good
- The Lofandi automatic hub shifts for you, so there's no downshifting before a climb and no fumbling with gears at a red light.
- A mid-drive Bafang puts out 120 Nm of torque, enough low-end grunt to keep a loaded bike climbing where lighter commuters bog down.
- The 960Wh battery is good for up to 55 miles, with a 1200Wh upgrade advertised at up to 85 if you want more range.
What to know
- At about 76 pounds it's heavy for a commuter, so hoisting it onto a car rack or up a staircase takes some effort.
- You're paying a premium, and a few rivals match its range and power for less if you don't mind shifting your own gears.
Velotric Discover M
What's good
- 100 Nm of torque from the mid-drive means steep streets and heavy loads don't leave you grinding.
- The 801.6Wh battery backs an up-to-95-mile claim, so most riders can go days between charges.
- A throttle plus switchable Class 1/2/3 lets you ride without pedaling or reconfigure for local path rules.
What to know
- At $2,499 you're paying a premium, and several commuters match the range for less money.
- Most of what you're paying for is the mid-drive and the build quality, so if you don't specifically want mid-drive climbing, the value case gets thin fast.
