![]() ![]() The difference between the 2 is the increased amount of power available with the 750 - when or if you want it, and yes, when the 750 is going faster or pulling harder than what is available with the 500 it WILL be pulling more power. The 750 watt motor is only using 500 watts! Kinda like the throttle isn't open as far as it was on the 500 ![]() Same identical bike, same identical factors in play as the earlier 500 test, but with a 750 watt motor at 10mph, still pulls XXX amount of power as it's doing the same amount of work the 500 was doing.

When acceleration or hill climbing is no issue, lets's say the 500 watt motor pulls XXX amount of power at 10mph (due to the factors in play at the moment). When adding a trailer to the decision, that makes it even more of a no brainer. Key Specs & Features: Top Speed: 21 mp/h (35 km/h) Range: 36 miles (58 km) Motor: 250W (450W peak) Wheel Size: 27.5 x 2.8 Pedal Sensor: 5 Levels PAS, Advanced Torque Transmission: Shimano 10-Speed Indexing Weighs: 22.1 kg (48. I'm not sure about how you feel about it, but when I point my bike at the opposite side of a busy intersection and tell it to go, I want to get to the other side as quickly as possible.įor that reason, given a choice between 500 and 750 watt motors, this is a no brainer. I took one of my spare packs and connected it to the charge port of another battery and went riding. My pannier bags cause some drag, but possibly not as much as a trailer since they are right behind my legs. That chews up watt hours, shortening range versus light weight hunched over head first riders. I suspect your trailer produces a lot of air drag. I bought 17.5 AH battery (840 wh) as I hope for 80 mile round trips, 40 with me pedaling unpowered, 40 with the motor doing all the work. Direct Drive motors have no gears, so high wattage is important in those to start up steep hills. Geared hub drives have internal gears allowing motors to run at more efficient high speeds. Mid drives have an internal gear that allows the motor to spin faster than the crank, and use the sprocket set of the bike, which allows more starting torque but wears out the chain. Torque multiplication matters in comparing motors. ![]() Shimano 7 spd, Avid disc brakes, 26 ballon. You sound as if you don't have 15% grades in your area.

Rear wheels take more than half the load of a normal bike, normally around 60 of the whole bike+riders weight Given you have a heavy motor in there as well. The mid-drive motor gets hot quickly, so it can provide support for less time when going uphill for example. If your hub and rim can take more spokes too, consider increasing the spoke count. Because the motor provides a lot of force on the chain and on the gear hub, more maintenance is needed to keep the bike in good condition. The bike often makes more noise than a front or rear hub motor. That is why you’ll notice the support a bit later. The Nakto Super Cruiser mega powerful electric bike, is one of the most elite fat tire electric bikes on the market.
