CYPLORE Kickstarter: Retrofit Your Road Bike, But Know the Limits
CYPLORE's 1.7 kg e-bike conversion hub promises light assist for road and gravel bikes. Small battery, real tradeoffs, Kickstarter risk included.
CYPLORE just launched a Kickstarter for what they're calling the world's lightest e-bike conversion system. The claim: 1.7 kg for hub + battery + sensor if you build your own wheel (FLEX), or 2.5 kg for a complete carbon rear wheel (ONE). That's lighter than Mahle's XS system at the same 2.5 kg, though Mahle's spec includes the external battery—so we're comparing apples to slightly different apples.
The hub motor is compact, fits 12 × 142mm thru-axles (standard on most modern road and gravel bikes), and outputs 250W peak with 23 Nm of torque. The bottle-style battery holds 111Wh and charges via USB-C in an hour. Range is listed at 50 km, which is optimistic and will shrink fast if you're heavy, climbing, or running it in Agile mode. The magnetic remote docks on the battery for charging, then mounts to your bar for ride control.


Here's the catch: 111Wh is a small battery. For context, that's about half what you'd find on a full e-bike. If you're using this to flatten out a hilly commute or extend a gravel loop, it'll work. If you're planning to rely on assist for an entire century, you'll run dry. The four modes (Smooth, Agile, Auto, Training) sound useful—Auto adapts to terrain, Training targets heart rate zones—but I can't verify how well the torque sensor actually responds until someone puts miles on it.
The system is designed for riders who already own a bike they like and don't want to buy a dedicated e-bike. That's smart. But you're still swapping your rear wheel, routing a cable, and mounting a battery where a bottle used to go. If you run two bottles on long rides, you're now down to one. And if you go with FLEX to keep your preferred rim, you're paying for a custom wheel build on top of the Kickstarter price.
CYPLORE is offering early-bird discounts up to 48% off retail, which is standard Kickstarter math. The system is IP65 rated (fine in rain, don't submerge it), connects via ANT+ to cycling computers, and has a companion app for Strava sync. I haven't tested it, so I can't speak to motor noise, drag when coasting, or whether the Auto mode actually feels intuitive. If you're curious and okay with Kickstarter risk, the specs are there. Just know you're trading bottle space and betting on a small battery.
