The 8 Best Electric Bike Conversion Kits
January 07, 2019: There are legal complications to converting your bike, and they need to be understood before choosing a kit. In order to be sold as an E-bike, the motor has to have a limiting switch that keeps it under 750 watts and about 20 miles per hour. However, the battery you choose will also affect speed, and this doesn't mean you can't turn off the limiting switch. In some places, it'll be fine, but in other areas, you'll technically be riding a motorcycle if you go beyond the limit, so you'll need a license and everything else necessary for a motorbike. Make sure you consult your local laws so you understand whether you need to limit your speed.
