How Much Power Do You Need?

The motor power you need for your conversion kit 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 Kirbebike, we offer 500W, 1200W, and 1500W conversion kits. With higher voltage, you can get more RPM and power out of a hub motor. If you're going to be doing short rides with your Kirbebike. 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. A 500W Kirbebike conversion kit also gives a decent hill climbing performance for a heavier set person, with this motor power you can expect around 18-22mph speed.

1200W motors are significantly more powerful than 500W and you will see a noticeable difference when it comes to hill climbing performance and acceleration. This motor type will bring a much better riding experience with our 48V batteries. We do offer bundle deals where we sell conversion kits with batteries. If your route is uphill and you need speed, we advise our 1200W Kirbebike conversion kits. The average speed you will get is between 25-30mph.

Now with the 1500W motors, you can expect an average speed of 35mph. We recommend this motor to our riders who enjoy the high speed and performance. 1500W will have slightly more torque than 1200W motor. 1500W hub motor is really going to carry most people to significant hills and faster acceleration.
