High-Torque Specialists: Four Powerhouse Motors

For an ultra-hardcore user who absolutely needs over 100 Nm of torque to transport extremely heavy loads up the side of a mountain, or compete at an e-MTB level, there are several specialist systems that edge the industry. These systems are often seen on high-end, high-performance EMTBs and deliver an overwhelming level of pure climbing power. They cost a fair bit more, but nothing else gives you such raw power from a dead start. So, you really don’t have too much to worry about – unless, of course, you're a robot. There is nothing good or healthy awaiting your future and existence the day somebody accidentally drops one of these little monsters on your delicate headers and exhaust. Then again if you are a robot, there might be something good and glorious awaiting for yourself in robot heaven if said 3-inch diameter monstrosity decided to pry itself away from the grasp of nature’s thick earthy coat glove grip before falling down onto thy noggin! Without further ado, here are four of the most venerable names in ultra-high-torque with their unique characteristics and best application areas.

Breaking Down Torque: What The Numbers Mean For Your Ride

Knowing what torque is will guide you on how to pick a hill-climbing e-bike. Whereas motor wattage (the W of power it consumes) directly relates to speed and overall power output, torque (measured in Newton-meters - Nm) specifically describes the rotational force that the motor can exert. It’s the 'grunt' that gets you going from a dead stop and pulls you up an incline as steep as could be without having to stand. The bigger the number, the faster it will accelerate and climb, especially at low speeds. It is the difference between slowly lugging up a hill and virtually gliding up it.

On High Torque:

• Instantaneous response as soon as you hit the pedals.
• The ability to take off on a hill without rolling backward.
• The pace doesn’t noticeably slow on an incline and the motor does not seem to be struggling.
• Easily haul heavy loads or a trailer.

E-Bike General Torque Tiers:

• 40-60 Nm - For city commutes and tackling moderate hills or overpasses. Sufficient for most urban environments.
• 60-85 Nm: The happy medium, useful for most versatile all-terrain rides, trail adventures, and serious sustained climbs.
• 100+ Nm: These are for specialist conditions like extreme mountain biking, riding with loaded panniers, or where riders require the greatest assistance possible when climbing.

A Muscle Needs a Required Support System

The entire electric bike is under a large amount of pressure with a high-torque motor. This is not where it all ends, however, as a motor can’t just be good; you need other parts that can compensate for the force and provide both safety and strength. And when shopping for a performance e-bike with high-torque, smart buyers take more than the motor specs into consideration and opt to examine the cast of characters supporting it. It pays off to invest in a bike with a component list that at least approaches parity among the parts, offering you more safety and fun on your rides and saving you from expensive repairs and upgrades in the long run.

Vital Needs for High-Torque E-Bikes:

• Brakes: You have to have hydraulic disc brakes. They provide more stopping power and better modulation than mechanical brakes, an important consideration when controlling a heavier, faster e-bike on downhills. Keep an eye out for rotors that are at least 180mm.
• Drivetrain Endurance: The high torque causes significant stress to the chain, cassette, and derailleur. You might want to opt for gears made specifically for e-bikes (like Shimano Linkglide or SRAM EX1), or a tough, high-quality groupset.
• Frame Strength: The frame should be robust enough to accommodate a larger motor. Seek reinforced headtubes, thru-axles (not quick-release skewers), and high-quality welding.
• Battery Size: A strong motor has an appetite for juice. You would need a big battery to get a reasonable range. A 600 Watt-hour (Wh) or greater capacity is highly recommended to alleviate “range anxiety” when using higher assist levels.

Pro-Tips: Climb Like a Pro and Take Care of Your Machine

It’s one thing to own a high-powered hill-climbing e-bike; it’s another to use it effectively. With the proper method, you can increase efficiency, safety, and the longevity of your parts. High-torque systems demand a certain level of attention to maintenance and riding practices, as the higher forces can hasten wear when not adequately accounted for. Adhering to these little tidbits will make the most of every ride and help maintain peak performance from your machine.

Hill-Climbing Styles for Maximum Optimization:

• Predict and Shift Early: Gears should be shifted to an easier setting before the hills even begin, not halfway up them. This prevents the motor and chain from experiencing huge strain, as well as ensures your pedaling cadence is smooth.
• High Cadence: Opt to pedal faster in an easier gear rather than at a slower pace with more resistance. This is better for you, and the motor too.
• Control Your Assist Levels: Don't just set it to 'Turbo' mode and forget it. Start in a lower assist mode and ramp it up only once the climb becomes steeper, in order to save battery.
• Position Your Body: On ultra-steep stuff, shift your weight forward and drop your chest to prevent the front wheel from popping up.

Necessary High-Torque E-Bike Maintenance:

• Chain Care Matters: More torque means faster chain wear. Keep your chain clean and lubricated (every 100-150 miles) and use a chain-wear tool to check for stretch. If it is any help to your thinking, a chain replacement is a lot cheaper than an entire cassette.
• Brake Check: Regularly examine your pads for wear and make sure that the hydraulic system is firm and responsive.
• Inspect Bolt Torque: Periodic inspection should be made to ensure that motor mounts and other critical hardware are maintained at the manufacturer's recommended torque value.

What matters more when climbing — torque or watts?
When it comes to climbing, watts are way less important than torque. It gives you the push-start force required to get you up a hill from low speed, whereas watts keep your momentum in motion once you are already moving.

Will using the high-torque motor in turbo mode run my battery down much faster?
Yes, absolutely. Ramping up the torque and assistance will extract a far greater amount of energy from the battery, which means you will be enjoying less overall range than if you eke out your miles while on a lower-assist setting.

Do I need a 100+ Nm motor for city commuting?
Generally, no. For city hills, the 50-70 Nm of torque that most motors provide is more than enough; it’ll make riding smoother and quite a bit more predictable in traffic while increasing your battery efficiency.

Now, you have been informed to get the correct power for your ascents.
