E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque, and others, like Bosch’s Active Line, are nearly silent. But, generally, all four make good options. Look for motor output (in torque), which will give you an idea of total power. Just like car engines, more torque equals more power off the line and more boost to your pedaling. But watt hours (Wh) is perhaps a more important figure to use—it takes into account battery output and life to give a more accurate reflection of power (higher Wh equals bigger range).


Let’s face it, at this price you likely won’t get a bike that hides its battery with any sort of elegance. Except for the Blix Vika+ folding e-bike on this list that tucks its battery behind the seat tube and the Propella that passes its battery off as a water bottle, most are stuck to the top of the down tube. Don’t expect to ride across the state on these, either. The highest range in this list is 50 miles, but most average about 30 to 35. Check the bike’s battery range before you buy to make sure it fits your daily needs.
Rambo Bikes includes a one-year warranty for the frame and components.  Rambo Bikes comes out of true love for the outdoors. Tailored to fit the needs of hunters, these fat tire bikes are made for all terrain, with emphasis on fields and woodland.  When you ride a Rambo, you are using a powerful, stealthy tool that allows you to travel whisper quiet into the woods to scout the land, carry gear, or simply enjoy the ride.
With most ebikes the choice of motor defines aspects of the frame geometry and to a lesser degree the suspension characteristics of the bike. Not with new Rock Mountain Altitude Powerplay. With its bespoke motor Rocky has been able to design an ebike that reflects the ride quality of a highly evolved 150mm trail bike. With instant power pickup, extended battery life and streamline proportions it’s not just the handling of the Rocky that will get you charged up for riding. It’s the best bike in this test by some margin, but we had an issue with the motor momentarily cutting and raising questions over it’s reliability.
