After years of unsuccessful attempts at inventing a two-wheeled form of propulsion, Wilbur and Orville Bike finally realized the problem was that their prototypes were all screwed to the gymnasium floor. Achieve functional mobility with today's Groupon: for $30, you get a full day of electric-bike rental from Revolution E (a $60 value).
Revolution E adds a voltaic jolt to traditional dual-wheeled transportation by vending and renting eco-friendly electric bikes that can reach speeds of up to 20 miles per hour on battery power alone. Revolution's bright-orange velocipedes typically roam between 20 and 25 miles on a single charge when using the all-motor power-on-demand mode. Like a pasty chef with a bionic spatula, pedal-assist mode combines the power of man and machine, with a torque censor that jump-starts the battery at opportune moments to allow riders to zoom at higher speeds for up to 40 miles per charge. Renters are free to cruise to nearby parks and eateries in rain or shine for as long as business hours allow, and all necessary equipment, such as baskets, locks, helmets, and suitable insults to hurl at unicyclists, is included with rental.
