I am fine with my 7ah piece of junk since I never go more then 40km. It's my sister that wants an e-bike so she can accompany her husband "Lance" on his 200k day rides. It looks like if she rides like me she will need 25ah which is expensive and heavy... but she's paying! Thanks everyone.
I get 40km (24miles) on a 36v 7ah SLA and BL36. Am I efficient? Since the SLA is actually 4ah because of the Peukert effect (ebikes.ca), should I get 3 times this range with a 12ah lithium?
Do any of the reputable hub motor kit companies make an all black wheel? I need a black rim, spokes and hub - preferably flat black for my Opus Classico (http://opusbike.com/pdf/Classico09.jpg). Thanks.
Thanks everyone. I found this at Canadian Tire for $13: http://www.canadiantire.ca/AST/browse/5/SportsRec/Marine/MarineBatteries/PRD~0790319P/Battery%2BMeter.jsp
