Teebike turns any bike into an electric bike
Teebike is a new French startup that wants to make it easier to switch from a good old sweat-based bike to an electric bike. With Teebike, you don’t have to get rid of your existing bike and buy a new one. You just have to replace the front wheel. The device detects when you’re on the move and a small electric motor kicks in. As a bonus, you can also lock the front wheel and enable an anti-theft alarm with the smartphone app.
