If you’re interested in an ebike, you have a couple of options: converting your existing bike or buying an electric version. Abadie says a bike suitable for conversion will have a powerful brake system, wider tires and a strong frame that can hold the motor and battery. He charges $800 to $1,200 to find the right parts and motors for a particular bike.
Electric Motor. Having a battery that will last long is just one piece of the puzzle. The electric motor should be powerful enough to move the bike on flat surfaces without any problems and to overcome some low-steep slopes. It will help you out on steeper slopes, it won’t let you down. If the motor or “the engine” is more powerful you’ll be able to accelerate faster and to reach a higher momentum. This will allow you to reach your destination faster and without you getting tired.
FRAME GEOMETRY EcoBike electric bikes have been specially designed with the daily commuter in mind. The frame is constructed from a high-strength, lightweight 6061 aluminum alloy that maximizes safety and durability. The enhanced frame design features comfort ergo-geometry that is more upright than a traditional mountain or road bike. Every EcoBike electric bike is outfitted with suspension on both front forks (except Vatavio) and seat post to deliver a smoother ride.
For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
