If you’re dreaming of an electric bike, but don’t want to let go of your old bike, an ebike conversion kit might be the answer. The Swytch Kit lets you pimp your bike with a 250W front motor wheel, which can propel you to speeds of up to 20mph (32kph). Your mileage will vary, but under ideal conditions and with the largest power pack, you can reach up to 20 miles (32km).
