![]() Īlso, has anyone tried refitting SLA cases like this one with NiMH packs? I think there was a brief reference to it on this forum quite recently, so I'll do a search for that too. ĭo you think the "Schwinn" izip has the same frame as the Currie izip at 50cycles? I'll have to do a search to find out more about the range. thats got me thinking now! Maybe I'll rethink my conversion plan. ![]() I've been trying to decide the best way to fit batteries to a standard aluminium mountain bike as part of a hub motor kit "fit": I wanted to avoid heavy batteries on the pannier/rear rack & currently my best option seems to be a "water bottle fixing" type case like the Bionx (only a bit bigger & a bit less stylish) but I'm concerned about the stress on the down tube of fixing 5kg+ like that, so having a bike frame which is designed to hold heavy batteries seems a distinct advantage, and with more budget ebikes available now like the izip, its an option really worth considering. I don't suppose there's any really noticeable difference when riding a heavier bike, and unless you have to carry the bike a distance, that shouldn't be any problem. I feel like I've missed a trick here: buy a bike built for SLA battery size & weight, then refit with similar weight NiMH for significantly longer range than you'd get even with a 36V 9Ah battery (maybe 1/4 to 1/3 more?). ![]() If you switch from SLA to NiMH I think you may need a different charger too? Check this if you're considering that. There's a video of another bike with a Currie motor at the bottom of that webpage link.Ĭurrie motors I think can be differently configured (internal gearing & power rating) and are also available separately in the UK with NiMH battery options. NiMH would be lighter Ah for Ah than SLA, and should have a longer life, but I guess if you want to use the same battery case/holder, you'd have to work out if the NiMH batteries would fit. It's been said here that its likely to be on the heavy side (since its a steel frame) at probably around 35-38kg including battery, but power output should be quite good - for more details search here for "izip". How far is the long journey you hoped to do Andrew? Some successfully carry a spare battery for such trips without problems. ![]() Also remember that the range will decrease over time (for NiMH at least, not sure about SLA?). The "Currie Izip" available here in the UK, which has been mentioned here in some detail recently.ġ5-20 miles (~25-33km) range with normal pedalling is given on the above site, and I'd guess thats on level terrain, so probably lower if used on hills. It actually looks identical to the men's version of ![]()
