In recent years, fixed-gear bicycles have become all the rage among urban bike messengers and hipsters. While “fixies” are not without their benefits – they can be stopped without a brake and ridden in reverse – they leave much to be desired for those used to mountain bikes. Most fixed-gear bikes only feature one speed; despite their lightweight construction and low level of maintenance, they require the rider to do every bit of the work.

An electric mountain bike such as the Xtreme electric bicycle sits at the other end of the spectrum. It can be ridden with or without a boost of electricity, making it suitable for leisurely rides on weekends or rush-hour traffic on the bike trail each morning. These bikes are perfect for people who like to have options, and their subtle, nondescript design certainly doesn’t scream “electric bike!”
