Another day, another novel approach to adding electric power to your bicycle. The Swytch is the latest offering in a seemingly constant stream of e-bike kits. And this one is billed as the lightest and most affordable E-bike conversion kit on the market.
The Swytch Instant E-Bike Kit carries its battery and control components in a handlebar bag, and drives the bike via a motorized front wheel. The kits cost between $300-$425 and add about 8.5-13lbs to your bike, depending on the version you choose…
The Swytch’s front hub motor comes built into a complete wheel – standard sizes available include 16, 20, 24, 26, 28, 29” and 700c, and other sizes are available upon request. The kit is said to fit almost any bike, but the motorized hub uses a 10mm (or optional 9mm) threaded axle with 100m spacing so bikes with thru-axles or 110mm boost forks aren’t going to be compatible. There is, however, a narrower axle available for Brompton folders, and the hub does include a disc brake mount.
The Swytch kit includes the handlebar bag & mounting bracket, a complete front wheel, brake sensors, and a pedal sensor. Installation looks fairly easy; users first swap out their front wheel, then clip the crank sensor ring around your BB shell, zip-tie the pedal sensor to your frame, squeeze the brake sensors onto your cables (FYI-there is an optional kit with different sensors for hydraulic brakes) and install the handlebar bracket and bag. The only step left is to secure the wiring and plug everything together.
The handlebar bag carries the battery, and has a control unit/display on top. The display shows your battery life and which of the five power assist levels you’re using. Plus the rider can turn on or off the bag’s integrated 500 lumen front light. The bag is waterproof, as are the sensors and the bracket’s electronic connections.
When the bag is clipped into its bracket it connects to the motor and sensors, so there’s no messing around with wires each time. Since the bag can be easily removed it won’t get stolen while your bike is left unattended. It also makes the bike lighter to carry up stairs, as you can haul the battery pack separately with its shoulder strap.
