The 52v 20Ah triangle battery provides over over 1,040 watt hours! This is truly your long distance battery. The reason we carry this battery is there are many bikes where you just cannot fit the downtube battery because the triangle is to small. Many bikes with full suspension cannot accommodate a down tube battery so this is the perfect solution. In addition, it is no small battery! I do not think there is a single production bike that comes with a 1,040 watt hour battery and if there was it would cost a lot more than our asking price. Look closely…this is not a “bag battery.” This battery is completely enclosed in a hardshell case. This makes for a cleaner install.
