There are some interesting measures taken by citizens of this fuel-hike-ridden world to devise some cost effective modes of transport. The Giant Twist Freedom DX Electric Bike for instance can take you 75 miles on a single charge. To reduce the confusion in your mind of how this bicycle works, let me make it known that it has three working modes. The Eco mode is all about pedaling and has very little inputs from the motor. The Normal mode will keep your feet active with s little help from the motor. The Sport mode will consume all that the motor has and is helpful when it comes to stepping up your speed and giving those feet some rest.
The thought of pedaling a 50 pound bike up a hill is painful enough but then you can always turn to the motor for some help. The bike costs $2,000.
