Everyone wants an electric bike but not everyone can afford it. The cheapest of electric bikes cost around $2000 and the alternative some companies provide either make your bike too heavy or are too expensive. However, all that is set to change because a Swedish engineering firm called Semcon has come up with a small gadget that does not cost you that much and makes your normal bike, an electric one.
The gadget costs only $100 so it is easily affordable. The company’s spokesperson Per Nilsson explains their approach in the following words: “There is, that we’re aware of, no low-cost alternative for turning your old bike electric. We saw an opportunity to develop a product that is inexpensive, low weight, easy to switch, and has enough power to support more bikers.”
The designers at Semcon hit upon the idea of a light-weight, detachable battery. Nilsson said that the riders would pedal off on their own when they start the ride. They optimized the motor to kick in when it is needed most; between 7 and 25 km/h speeds. This enabled the engineers to keep the engine smaller.
The add-battery is attached to a magnet and is easily maneuverable. It can be removed, charged and even put on another bike. The design employs an Arduino and can connect to Wi-Fi to provide access to the navigation apps, or the anti-theft tracking systems.
