    My daughter is looking to electrify her bicycle. She rides 3 miles up hill to work. Not much of a grade, but almost continuous.

    Is there anything reliable on ebay?

    Looking for plug and play, complete kit. 250.00-ish?

    Help, and thanks!

    The Hill Topper kit with SLA batteries and 10 mile range sells for $400 on Ebay, I think. Sick bike parts also has an electric kit that is priced pretty low.

    Looks like I am going to have to make a "homebuilt" system to stay under budget.

    Thanks!

    Search for some threads by "Deacon". He was able to piece together some inexpensive electric systems.

    Scooter motors and controllers are low tech but still about 80% efficient and work great, plenty cheap on ebay. I say go with a 36-48V system and 20 miles and 20mph are realistic.

    You aren't going to find anything decent that includes a worthwhile battery for $250. And remember the $'s are in the battery. Not that you really need it but a 48V 20Ah battery can be over $700.

    We have been in slow development mode for 2+ years, by slow I mean part time here and there and completely delayed on purpose as battery technology evolves. We have actually put LiFePo behind us for now and are really studying NMC Li batteries. Smaller and lighter yet. Flipping amazing actually. I have a 36V ~800W system on a bike that goes like a ravaged ape. 48V, ~1200W? Both hands on your bars fast.

    Our kits will be shifter kits. IOW - use your gears, we stick with our company core belief - that's what they are there for. Peddle every once and awhile and REALLY save battery power. As we buy and try, and buy more volume and try we are now onto a different manufacturer of controller as well. These projects burn cash even if we go slow. But we have stuff filling shop#1. We need to sell stuff!!

    That's where the 24V system comes in. We have decided our niche will not include 24V systems, they work fine - they just don't have the kick the higher voltage systems have, but the batteries are more reasonable. This kit comes with every thing you need, but is a DIY set up. Low gear should pull her along fine.
