Aventon Pace 4 vs Cyrusher Flex Step-Over
Two commuter e-bikes at a similar price, compared on the same normalized specs. Both scored by us, both reviewed in full.
The verdict
Same price and same Genius score, so this comes down to whether you need power and payload (Cyrusher) or a lighter bike with more range on paper (Aventon).
Buy the Aventon Pace 4
Buy the Aventon Pace 4 if you want the lighter bike to haul up steps or into an apartment, and you'd rather have longer claimed range than raw power.
Buy the Cyrusher Flex Step-Over
Buy the Cyrusher Flex Step-Over if you actually climb hills or carry heavy loads: 27 Nm more torque, a bigger motor, wider tires, and 50 lb more payload capacity, at the same price.
The differences that matter
- Cyrusher Flex Step-Over pulls harder from a stop and on hills, by 27 Nm of torque.
- Cyrusher Flex Step-Over runs a 250W bigger motor on continuous power.
- Aventon Pace 4 is 10 lb lighter, which you notice lifting it or carrying it up steps.
- Aventon Pace 4 claims 11 more miles of range, though both figures are the manufacturer's optimistic "up to" number.

The short version on each
Aventon Pace 4
What's good
- The low step-through frame makes getting on and off easy, whether you're in work clothes, hopping off at a light, or loaded down with groceries.
- A big 733Wh battery backs up the claimed range of up to 70 miles, so most people can go several days of commuting between charges.
- A throttle lets you ride without pedaling up to 20 mph, handy for pulling away from stops or resting your legs.
What to know
- The hub motor puts out steady rather than punchy power, so steep climbs feel like more work than they would on a higher-torque bike.
- There's no suspension and the tires are a fairly narrow 2.1 inches, so this is a smooth-pavement bike, not one for rough roads or trails.
Cyrusher Flex Step-Over
What's good
- Unusually strong climbing muscle for a commuter, with 87 Nm of torque and a 750-watt motor
- A 720Wh battery and up to 59 miles of claimed range, enough for several days of commuting between charges
- Tektro hydraulic disc brakes front and rear, the kind of stopping power a fast bike should have
What to know
- As a Class 3 bike at 28 mph, it's barred from some multi-use paths that limit e-bikes to 20 mph
- Cyrusher lists two different payload numbers, so the true limit takes a bit of digging before you haul heavy loads
