Amp hours refers to the amount of electrical charge the battery can product in an hour, while voltage determines (in part) the power output of the battery.
Most e-bikes and e-scooters will have lithium-ion batteries.
In the UK, the maximum legal power output of an e-bike for use on public roads and footpaths is 250W.
In the UK, the legal speed limit of e-bikes is 15.5mph.
The higher the torque, the easier it will feel when pedalling.
Anything over 30nm is more than sufficient!
The range of any e-bike or e-scooter is highly sensitive to the weight of the rider, style of riding, terrain traversed or level of assistance used, to name a few.
Torque sensors measure the force applied to the pedal, adjusting assistance based on rider effort, while cadence sensors determine pedal rotation speed, regulating assistance independently of force on e-bikes.
Torque sensors are considered to be smoother than cadence sensors, adjusting to the rider's inputs.
Cycling in a lower gear means less pedalling effort and less speed.
Cycling in a higher gear means more pedalling effort and more speed.
Most e-bikes will come with 7 or 8 gears.
