Aventon Soltera 2.5 vs Rad Power Radster Road

The Soltera 2.5 is the lighter, simpler city commuter at 46 lbs with a 350W motor, 36V battery and a 20 mph cap, so it suits riders who want an easy-to-carry, low-maintenance bike for short urban trips. The Radster Road is the faster, longer-legged machine: a 750W rear hub motor, 720 Wh battery, Class 3 28 mph top speed, 8-speed drivetrain and an 80 mm suspension fork. Owners of the Soltera praise its light weight and torque sensor; Radster Road owners like the speed and range but note the 74 lb weight.

  • Choose the Aventon Soltera 2.5 if you want a light, nimble city commuter that is easy to carry up stairs and store, and you do not need to ride above 20 mph.
  • Choose the Rad Power Radster Road if you want more speed, a bigger battery for longer rides, a suspension fork and a full 8-speed drivetrain.

Questions and answers

Which is better for a hilly commute?
The Radster Road. Its 750W motor and 8-speed drivetrain give more climbing power and gear range than the Soltera 2.5's 350W motor.
Which is easier to carry up stairs?
The Soltera 2.5 at 46 lbs. The Radster Road weighs about 74 lbs, which is difficult to lift regularly.
Which has longer range?
The Radster Road. Its 720 Wh battery is rated for 25-65 miles, while the Soltera 2.5 is rated up to 46 miles.
Is the Radster Road worth stepping up to?
Yes if you want Class 3 speed, suspension and more range. If you mostly ride flat city streets and value light weight, the Soltera 2.5 is enough.
Do both have hydraulic brakes?
Yes. The Soltera 2.5 uses hydraulic disc brakes and the Radster Road uses Tektro hydraulic disc brakes.
Which is better for a smaller rider?
The Soltera 2.5 comes in three frame sizes with a lower step-over and lighter weight, which suits smaller riders better than the Radster Road's mid-step full-size frame.
