For commuter and touring e-bike riders, often lugging a load or perhaps travelling with a trailer, the TQP’s HPR 120S could be ideal. Perhaps an innovative boutique frame brand will be daring and integrate it into a road-going e-bike application soon. A single mid-drive motor standard would change everything
That's the common wisdom, anyway. In practice, engineers have found that vehicles with hub motors simply need to have their suspension "tweaked" to compensate for the extra unsprung mass, and this can even lead to an overall improvement in handling. Safety Hub motors may be implemented with direct-drive or planetary gears. [16] They rotate the wheel either through an axial, inrunner, or outrunner rotor design, with either brushed or brushless commutator design.

Running high voltage outside the chassis can be avoided by using near-wheel motors, which have similar advantages to in-wheel motors. With the SL 1.1 motor, Specialized has shown how light a high-performance road e-bike can be. The company’s Turbo Creo SL is powered by a 240w motor and targeted at those road riders who have the fitness, but not the flexibility of schedule for those five-hour training rides.

Isolated hub motors are something of a futuristic ideal. For the time being, hub motors are more likely to be retro-fitted The main downside of a front hub relates to the fact that on most bicycles, a majority of the rider weight is on the rear wheel rather than the front wheel, so the amount of traction available on the front wheel is not as high and it can be possible for the wheel to skid out at full throttle. Riding on pavement this only becomes an issue at pretty high power levels (>1500 watts), but when climbing hills on loose gravel or dirt roads, you can end up with the front wheel skidding pretty easily even at fairly modest powers unless you deliberately lean over the handlebars. The worst took a while to stop, needing more compression before the brakes engaged. They were also noisy and grating. Ease of use

The Japanese cycling component giant was never going to be uninvolved with e-bikes. Although Shimano is notorious for its conservative product development, the new EP8 mid-drive motor has been worth waiting for.
How does a brushless DC (BLDC) motor work?
In general, we find that geared motors are most often preferred by people who value their smaller size and weight, who require a hub with good efficiency during hill climbing, and for whom the ability to coast with zero drag outweighs the benefits of regenerative braking. torque (and low speed) or high speed (and low torque) depending on whether you're starting off from a standstill, racing along the freeway, driving slowly uphill, or whatever. Hub motors have to be able to produce any combination of speed and torque Electrical Machines: Fundamentals of Electromechanical Energy Conversion by Jacek F. Gieras. CRC Press, 2016. A great overview that puts brushless motors (covered in Chapter 8) in the broader context of electromagnetic devices such as electric motors, generators, and transformers.
