What’s the Greatest Ebike Motor? Mid-Drive and Rear Hub Motor Professionals and Con

With a number of competing data on the market, it may be onerous to type out what kind of ebike motor system may finest suit your wants.

Fortunately, we’re a model making high quality ebikes with each mid-drive and rear hub motors; so we’re properly positioned to offer you some unvarnished execs and cons of each methods. As for front-drive motors, we’re involved that they are often harmful, as low-quality software program can result in a entrance wheel making use of torque as you flip or journey throughout areas with low traction; a state of affairs that may result in lack of management and harmful crashes.

However first, a word that motors are just one issue contributing to the journey really feel and efficiency of an electrical bike. The standard of the controller, firmware and software program are additionally key! They interpret the enter from onboard and exterior sensors – like torque and cadence sensors – driving the motor in accordance with pre-set parameters together with rider-selected help ranges. Even the most effective motors can appear jumpy or tough if the ability management system isn’t well-designed. Excessive-quality management methods like these from Acer used throughout our ebike line ship essentially the most pure journey really feel and energy, it doesn’t matter what motor they’re linked to.

Now to look at among the most necessary advantages that these motor methods present to riders:


Rear hub motors win the affordability prize, with good high quality methods being obtainable on bikes from round $1000 on up. With extra advanced building, extra sensors and (after all) devoted body designs, high quality mid-drive motors aren’t discovered on many ebikes underneath $2000, making them out of attain for many riders entry-level ebikes.


Wattage is necessary, however don’t neglect in regards to the torque output of the motor system on the ebike you’re contemplating. There are many rear hub motors with main wattage output within the 500-750 watt vary that solely output a nominal 50-60Nm of torque. Evaluate that to most 250w mid-drives the place 60-80nm of torque is usually on faucet. Should you stay someplace hilly, or have a number of stop-start using in your routes it is best to take into account that mid-drive motors will likely be simpler to journey in these situations. *Additionally, word that motors over 750w (1hp) aren’t ebike authorized in most US localities. Should you stay someplace extraordinarily hilly, you in all probability want a high-end hub motor or mid-drive as low-end “direct drive” hub motors could not give you the torque wanted to climb steep hills.


The pure and highly effective increase obtainable from mid-drive motors with torque sensors is their major efficiency edge over hub motors. Think about typically larger torque outputs for quicker acceleration, weight properly balanced within the heart of the bike and you’ll see why most ebike fans get pleasure from mid-drive motor efficiency.


It’s just about a tie right here between motor varieties. We chosen our Acer and MPF motors as a result of they’re constructed for sturdiness. We selected to concentrate on longevity as we’ve seen loads of experiences of failure in decrease weight and cheaper motors of each hub and mid-drive varieties. We’d slightly provide a greater unit and a 3-year guarantee than save a pair hundred grams! All in all, the important thing to minimizing system upkeep is to journey evenly. On many methods; together with ours, the motor outputs peak help once you’re pedaling between 80-100rpm, so sustain your cadence and use use the help perform like a gear changer to cycle by means of completely different ranges of increase from 1-4 (or 5) as you construct pace, and also you’ll reap the rewards with the most effective longevity and lowest upkeep on your total powertrain from motor to belt and gears.

We see the upsides of every model of motor and have fashions that make the most of each varieties. Everybody’s transportation wants differ, however now we have a pair suggestions that can assist you in your method now that you’ve got a greater grasp of the fundamentals:

If you may be pulling cargo or scaling hills you’d in all probability get pleasure from the additional torque within the mid-drive motor. However for those who’re searching for the only resolution to get round, the hub motor is for you.
