Shortly after World War II, a French manufacturer by the name of Solex started selling mopeds. These were not your "typical" moped that looks kind of like a motorcycle with pedals—the mopeds made by Solex were essentially bicycles with a small two-stroke engine mounted over the front wheel that could propel the rider around 100 km on a single liter of gas mixture. The downside: Solex mopeds were loud and cumbersome to ride due to the weight distribution, and they never really caught on in North America.
Clip, a startup based in Brooklyn, New York, has come up with its own twist on the Solex. Its only product, the eponymously named Clip, is a friction drive unit that attaches to the front fork of any bicycle, turning it into an e-bike. At $499 for the Commuter model and $599 for the Explorer, it is a relatively inexpensive way to turn just about any bicycle into an e-bike for a fraction of the cost of a new one.
Weighing in at 8.8 lb (4 kg) for the Commuter model (the Explorer is a pound heavier), the Clip is at its essence a portable friction-drive. A detachable controller mounts on the handlebar and the unit itself. The Explorer model, the one we reviewed, has a 192 Wh battery that takes an hour to fully charge. Its range is pegged at "up to 12 miles," a claim that is pretty accurate based on our testing, and the top speed is 15 mph. The Commuter model offers half the battery capacity, charge time, and range.
Twelve miles may not seem like a lot, especially in contrast to e-bikes with ranges that exceed 70 miles. But the Clip isn't designed for long, leisurely rides. It's a tool for folks who want to resuscitate old bikes that might be gathering dust in the garage. In my case, that bike is a 1997 Gary Fisher Marlin mountain bike that is now only ridden once or twice a year.
