There is almost nothing healthier than pedaling along on a bicycle. On the other hand, comfort quickly wins when there is an opportunity. Put positively: progress is coming to the bike world.
The Rubbee kickstarter project is the name of the game. Costing 810 euros, the 800 watt motor is driven by a battery with 20 ampere hour capacity (rechargeable in 2 hours), providing an range of 25km (16 miles) at 25 km/h (16 mph) peak speed.
The motor’s energy is sent to the bicycle’s back wheel via a rubber roller. Something worth considering for bikers commuting to work.
