e bike, yo bike?

I own a Synergie ebike-It cost £300 last year,and by using it for work(good weather/summer) and short shopping trips,I've saved that much in taxi fares already! The bike has 5 speed Shimano gears,and folds so It can go in the boot of a car/bus.. It can go 3 ways-unpowered-just you and the gears...secondly,on battery power alone-there's a twist grip throttle on the handlebar..just twist and go..however,an ebike is NOT a motorbike-to qualify legally to not require tax,license or Insurance,(and a crash helmet)it's speed and power are limited (to 15mph under motor power alone..faster is possible by pedalling and use of gears)you may have a problem getting up hills under motor power alone..which is where the third mode comes in...called pedelec PED(al) ELEC(tric),ie.when you pedal,the motor gives you a boost to get up a hill,and extends the range you can travel with little effort on the level..Range is around 20+ miles per charge.There is one legal requirement (UK) that the rider is 14 or over..I could recommend these machines to any cyclist or commuter,Male or Female.
