I may purchase a 2011 Kona Ute Electric that appears to only be made in 2011. It has:

250 watt front hub motor (8-fun brushless geared)
24-volt, 13Ah
Controller FMN/Wettsem
Battery HiTech Energy
Charger HiPower
Dropout Sensor TMM4, dropout sensor

I understand that the bike is in fine condition, but I'm told by a friend that is familiar with battery systems that you really just don't know for sure - and replacement parts are tough to get.

So, would you do it? If so, what questions would you ask? Do these names look common and can they be replaced easily if necessary?

Newbie questions, but i'll continue to research while I await responses.
