How Much Power Do You Need ?

The motor power you need basically depends on some conditions like your expectations from the kit, the terrain, the weight, weather conditions, and how fast you want to go. At eBikeling, we offer 500W, 1200W, and 1500W ebike hub motors. With higher voltage, you can get more RPM and power out of a hub motor. If you’re going to be doing short rides let’s say 15-20 miles like you’re going around on a neighborhood, local beach, or a short commute. In this case, we most likely recommend a 500W motor but we wouldn’t say stay away from 1200W or 1500W if you personally enjoy the higher speed. 500W also gives a decent hill climbing performance for a heavier set person, with this motor power you can expect around 18-22mph speed.

Sparking When Controller Connected to The Battery

When connecting a Li-On battery and ebike DC controller, oftentimes we see a spark on the wire. The reason why is the surge current that flows into the controller because of the large capacitor that gets charged. Sparking that you have is pretty normal. The controllers with large capacitors may have this issue, it’s because you’re filling the capacitors quickly and that’s causing the spark. To prevent this event you can use an on/off switched battery. It will eliminate the spark that you see. Although some ebike users proceed with another option to eliminate the sparks. They use a pre-charge resistor. Pre-charge resistors slow down the current by the capacitors in the controller ...

What are power cut-off brake levers for?

Power cut off brakes are for mainly safety purposes. They bring additional safety to your ride. Now let’s see how they work. There is a sensor that when you have pulled the brake lever, sends a signal to the controller to turn off the motor. But do you actually need brake cutoffs? It depends where you’re riding your bike. If you’re riding on a crowded bike path or slowly making way through traffic jams, you may need to go very slowly in these circumstances. Also, it’ll protect the rider in case of emergency braking, even though you forgot to release the throttle the brake sensors will cut off the power on the throttle. The sensors override the throttle because there is no point to power the motor while braking. You need to slightly apply the brake levers to...
