With its sleek design, the TranzX Works downtube battery is made to pack an enormous amount of power in small package. The design includes the lithium ion electric bike battery and a bracket that easily bolts onto the downtube bar where most water bottle holders normally sit. This makes it especially easy to remove and replace for recharging. For basic bike conversions, it provides power to the motor without a ton of extra weight. Simply snap it in for hours of riding!
