Looks like an interesting product. It appears there is no spare battery though and the range is somewhat limited. It would be handy if you have several bikes.
Like an e-bike knight jousting down the road, the Clip kit’s elongated frame and shell jut out past the front of the bike. However, the entire kit is also removable so that riders can easily stow it in a bag or carry the device inside for charging. The internal battery is rated at 144 Wh, which is rather small compared to the 500-700 Wh e-bike batteries commonly seen today.
But with the lack of a throttle, the manufacturer claims that its pedal assist functionality still offers decent range of 10-15 miles (16-25 km), or enough for around a 45-minute commute. And with a claimed recharge time of just 40 minutes, even a quick stop at the coffee shop should replenish a decent amount of your battery charge. The Clip kit allows the e-bike to fit into Class 1 designation in the US, meaning it cuts assist after reaching 15 mph (25 km/h). It also features a 450W power rating, so it should feel a bit more lively than typical European-legal e-bikes with 250W power limits.
Clip is pre-selling its kits for $399 and has already sold out the first round, meaning anyone else getting in line will have to wait for delivery this summer.
