Bike Kit Adds Electric Power at Just 3.75 Pounds

Your beloved bike could get an electric boost without turning into a heavyweight.

The Cyplore conversion kit transforms regular road and gravel bikes into ebikes while weighing just 1.7 kilograms (3.75 pounds). Former designers from Xiaomi and Samsung created the system to help cyclists who want electric assist but don't want to buy a whole new bike or add significant weight.

The kit comes in two versions. The Flex model includes a 250-watt hub motor that riders can build into their own rear wheel, plus a lithium battery that mounts on the bike frame. The One model arrives as a complete wheel with the motor already installed and ready to ride.

Both versions deliver the same performance. Riders get 50 kilometers (31 miles) of range per charge, with the battery recharging via USB-C in just one hour. The motor provides electric assist up to 32 kilometers per hour in North America or 25 kilometers per hour in Europe, matching legal limits for each region.

A magnetic wireless remote lets cyclists switch between four riding modes without taking their hands off the handlebars. When riders want pure pedal power, an internal clutch completely disengages the motor so it creates zero drag.

The Bright Side

This technology makes sustainable transportation more accessible to people who already own bikes. Instead of spending thousands on a new ebike or leaving a perfectly good bike unused, cyclists can upgrade what they have. The lightweight design means riders keep the nimble feel of their original bike while gaining the option to cruise up hills or extend their range on longer rides.

The system also connects to cycling computers through ANT+, tracking speed, battery status, and ride history. Early backers on Kickstarter can get the Flex for $599 or the One for $779, compared to planned retail prices of $1,149 and $1,519.

Making existing bikes electric rather than buying new ones keeps more bikes in use and fewer in landfills.
