REM, a handheld "power stick" that works completely independent of the user's skateboard, might be a good alternative to electric skateboards

 

Currently the subject of a Kickstarter campaign, REM is being developed by Barcelona-based startup Limitless Propulsions.

The setup has a top speed of 25 mph along with a complete lack of brakes – the onus is upon users to stop themselves as they normally would, without a motor.

Power is provided by a 44.4V lithium battery which is claimed to be good for a range of about 12 miles per charge.

Of course, if the battery runs out, the skateboard can still be used on its own. In fact, one of the big selling points of REM is the fact that it leaves the user's board light, sleek and unaltered, instead of being weighed down and cluttered with a motor and battery.
