Jodi and Samuel turn normal bikes into e-bikes with their own batteries

Convert a normal bicycle into an e-bike. That’s what Jodi Kooijman and Samuel IJsselmuiden do in Den Bosch. With their start-up Swugo they want to enthuse as many people as possible to leave the car at home and get on a bicycle. “You can have an electric bicycle within fifteen minutes,” says Jodi while tinkering with a so-called Heyfiets.

Jodi, who is originally from Dubai, and Samuel who was born in South Africa, got to know each other during their studies in the Netherlands. In two years they wanted to make ‘something in traffic’ more sustainable.

“We want fewer or no cars in Dutch cities. During our research we noticed that the electric bicycle is already a good alternative, but it can be improved”, says Jodi. “When the battery of an electric bicycle needs to be replaced, people often buy a new bicycle. Logical, because a battery costs hundreds of euros. But there is often nothing wrong with the bicycle itself. That can be done cheaper and more sustainable.”

“Our battery can be placed on any bicycle.”

So the boys started designing batteries themselves. “We first wanted to optimize the batteries of electric bicycles so that they last longer. But that is very difficult, because every electric bicycle has a different battery. Just like smartphones, for example,” explains Samuel. “That’s why we designed a battery ourselves that is a lot more durable and therefore lasts longer. And: it can be placed on any bicycle.”

So two birds with one stone. A battery that lasts longer and can also be mounted on any bicycle.

In a workshop in Den Bosch they show how they do it. Samuel replaces the front wheel of the old bicycle with a new one with motor. He also attaches a battery to the bicycle frame and a sensor is built into the pedals. Within fifteen minutes the bicycle is transformed into an e-bike.
