Product Information

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 Ulrich, Lawrence (23 September 2007). "They're Electric, but Can They Be Fantastic?". The New York Times. Mountain bike designers have readily adopted the new EP8 system, but Shimano says that its compact size and linear power delivery, calibrated to run seamlessly at high cadence, is perfectly adaptable to commuter and touring bikes, too. Small hub motors start at about 1.5kg whilst mid-drives tend to be around double that. Are some motors more reliable than others? In a geared hub, the motor spins internally at a high RPM and a planetary gear transmission reduces this to the low RPM of the bike wheel. This allows for a relatively small electric motor to provide substantial wheel torque. Geared hub motors usually weight between 2-4kg and are small in diameter, allowing them to remain pretty discrete on the bike. For a number of reasons, almost all geared motors also include a freewheeling clutch so that the wheel will spin freely and not turn the motor over if you are coasting.

They all get the basic job done All the e-bikes we tested took the effort out of cycling to some degree, although we found big differences between the best and the worst. If you're just looking for something to use occasionally to get from A to B, and don't have big hills to climb, you don't need to break the bank. Holloway, James (20 February 2012).

Though not exactly hub motors as such, each wheel was nevertheless powered by its own separate 10,000 rpm electric motor. Photo by courtesy of NASA Marshall Space Flight Center (NASA-MSFC). PedalEase electric bike conversion kit for Brompton Bike. 36v 250w front hub mini motor 75mm built in double butted alloy Brompton size wheel. Complete kit with battery and charger.Most of our bundled conversion kits come with a suitable field-oriented controller. For the Ready-To-Roll setups this is a Baserunner that fits inside the cradle of a downtube battery. The DIY and High Voltage kits have options for the higher power Phaserunner or Frankenrunner controllers as well which can be mounted externally. Previously we also offered a line of more generic Grinfineon controllers as a low-cost option, but have discontinued carrying these due to availability and reliability challenges. Ready-to-Roll or DIY? Please Note: The motor power rating of this e-bike exceeds 250 watts and has a speed greater than 25 km/Hr (15.5 mph). This is a high-power bike for OFF-road use only and cannot be used on the public highway. Under the Road Traffic Act 1988 (and related legislation) it cannot be used anywhere off-road, except on private land with the landowner's permission. Durable & Convenient]: Aluminum alloy frame for durability and stability, can support a heavy weight up to 220 Lbs; drive system without moving chains or gears for anti-friction; thumb throttle with 3 indicators for displaying battery status, perfect to avoid stopping working caused by low battery suddenly, you can charge the battery in time High cadence and torque outputs can increase the risk of overheating a mid-drive motor. Bosch engineers have meticulously engineered the Cargo Line’s casing, paying special attention to surface area and shape. This helps it to optimise ambient cooling, even at low speeds.

Pioneer for bicycle motors

The motor isn't a replacement for having gears While the motor helps, we found that electric bikes with only one gear didn't perform as well on our hill tests. If your daily commute or favourite cycling route has some big hills, make sure you get an e-bike with gears. 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. Regenerative braking involves using the motor as a brake to assist in slowing the bike down without wearing your mechanical brakes. This typically results in a 3-8% increase in your range from recaptured energy and a massive reduction in the frequency with which you need to adjust and replace your brake pads. There is no downside or tradeoff whatsoever to having regen if you have a direct drive hub motor. For some of the geared motors we offer the option of regen or not, and depending on how you feel about freewheeling vs reduced brake wear you may be swayed one way or the other.

The Zehus system contains everything you need in one large shiny rear silver hub. It has its shortcomings - namely a small battery that is not removable - but the latest perfromance-upgraded version features extra torque making it a much better hill climber than predecessors.

Powerful Brushless Motor]: Electric bicycle rear wheel conversion kit features 48V 1000W brushless and gearless hub motor for efficient running; fit for any 26" bicycle frame with 5 5/16" rear dropout spacing, easily convert your bicycle to electric bike and reach the maximum riding speed of 45 KM/H, suitable for regular bicycles used on commuting and short journeyUS Patent 6,974,399: Hub motor mechanism by Chiu-Hsiang Lo, 13 December 2005. A hub motor with a built-in planetary gear and clutch. Engineers have managed to do what all riders desire from their mid-drive motors, be lighter and more powerful. Shimano managed to trim 300g of weight from the EP8000 system, whilst making it 10 per cent smaller, too.
