A major ranking criterion for electric bikes is the torque rating of the motor. Generally speaking, bikes/motors with higher torques are sold at a higher price than bikes/motors with lower torques. ... So the torque that matters is the final torque on the wheel axis, not the torque output on the motor axis.

Why do electric bikes have more torque?

In an electric bicycle, torque is the ability to rotate the rear wheel. ... Higher torque will rotate the wheel easier and create more acceleration, especially from a stop. This means a bike with higher torque is easier to get going from a stop.

What is Torque on electric bike?

It measures your actual force on the pedal, sampling at 1,000 times per second over the entire pedal stroke. A torque sensor measures how hard the rider is pedaling to determine how much electric power to push to the bike. The harder you pedal, the more power it gives to the motor.

How is electric bike torque calculated?

F=m*a with m being the mass of the biciycle of 150kg and a the acceleration you desire to be a=dv/dt=[25km/h]/[10s]. Please add the correcting factor for the different units :-) From the resulting F and the bicycle's tire diameter r you can calculate the torque M needed at the tire's center from M=r*F.

Which electric bike motor is best?

Rear motors are best for riders wanting or needing more power, or those looking to incorporate a throttle. There are also some new electric road bikes with small 250W rear hub motors that can be very stealthy with an integrated battery for a clean, traditional appearance.

What is the quietest eBike motor?

Brose gets the #1 spot. Some Bosch are very quiet but not all. The Trek (and all OEM mid-drives AFAIK ) has a geared motor (look at the ebikesca tutorials for an explanation), and they're noisier than direct drive (DD) motors (mostly confined to the DIY crowd, Stromer and other hub-drive systems).

What is the fastest eBike?

The EB-01 is the most powerful and fastest electric bike in the world, but it is not the only one. Other fast ebikes worth mentioning are Revolution from High Power Cycles company in the US (max speed: 55 mph, cost: $10,000), and STEALTH B-52 from the Stealth company in Australia (max speed: 50 mph, cost: $6800).

What size motor do I need for an electric bike?

So for that type of rider, I would most likely recommend a 250-watt motor. Now, I wouldn't say stay away from 500-watt because I personally enjoy the power of a 500 watt. Now, but it's not necessary. If you're gonna be doing shorter rides, maybe less than let's say 15 miles or even 10 miles 250 watt is a great option.

Is 250 watts enough for ebike?

If you're 100 pounds, a 250-watt motor may be enough for you. But if you're 220 pounds, a 500-watt motor might be better for you because the top speed somebody on a 250-watt motor at 100 pounds can hit might be pretty close to the top speed somebody that's 250 pounds on a 500-watt could hit.

What does NM mean on an electric bike?

Motor Torque is the characteristic which reflects the traction (thrust) and is important for climbing up hills. The traction force equals Torque divided by wheel radius (F=T/R). The more torque at the wheel gives you a higher grade-ability.
