This Lemmo One, by industrial design and mobility firm Springtime, is an "E+bike." It's so named because it's an ordinary bike until you slap the removable battery onto it. "Through a break-through and patented innovation, the bike can be both ridden as an E-bike as well as a conventional bike," writes Springtime. "This is achieved by a removable battery pack (Smartpac) and by adding a clutch to the hub motor, which can completely take away any resistance from the motor (Dual Mode Hub).""The Smartpac can easily be taken off the bike and be used as a power bank for your mobile devices." The bike is up for pre-order at 450 (USD $472), but it appears to be EU-market-only.
