--Introduction, skip if you must--
Hello! First, a brief introduction. I've been an avid cyclist for years, but just passed by a store in Eau Claire about a month ago which had electric bike conversion kits. I've never really heard of them or seen them before, but it was very interesting. Being in university and *really* tight on money, but deeming it a good investment (which it is, or was.. used it a lot and would love to continue doing so!) Did some research on the kits (apparently not enough), and ended up purchasing a Crystalyte Roadrunner front drive kit.
There were some big problems though. I wanted more range than 25km, and the salesman told me that the standard kit wouldn't do it, but the extended kit would, although it was really heavy.
So then he told me about this 48v battery they could make, which would weigh only a little more than the standard but get much more range. I didn't really know much about this particular battery as i'd only researched the others, but that sounded alright. The only thing is, the next day he brought out the battery and it weighed just as much, if not more than the extended.
Its now 3 weeks later. On the first day of using the kit I blew the rear tube on my bike and had to replace it. A week later I crushed the rear bike rack which has a 150lb weight rating. Now, the bag holding the batteries is ripping at the velcro straps.
I'm not sure what to do anymore. I can't find any stronger racks, nor afford to constantly replace parts (not to mention the waste), and I think that this system is just too heavy for the aggressiveness of my riding, although the speed is great and the range is as well.
I'm at end with the project though, and about to go in and give away the batteries and such so that I can buy a smaller lithium pack.
--Can you help answer these?--
I realize that the 37v lithium packs won't go as fast as the 48v SLA pack, but:
Both are 10ah. Will the lithium being only 37v reduce my maximum range, or just mean that it'll take the bike longer to go the same distance?
I'm worried about how I ride the bike. The project was made with being able to switch out the front hub for actual XC riding when wanted, but i'm used to aggressive riding. Will the hub motor stand up to going off curbs, over speedbumps, and down stairs or should I tone down riding?
And, i'm looking to get a new bike next year. I know that the front hub puts more strain on the fork, but is suspension possible if a better fork is used like a Rox Shox Recon 351?
Any help would be really appreciated.
On a bright note, this thing has my girlfriend hooked too and we'll both be riding them around next year!
