    5 wires throttle to 3 wires controller?

    Dear all, My bike has a 5 wires/2 plugs throttle installed but I want to up rate the controller with an ecrazyman controller which only has a three wires/1 plug throttle connector. What should I do? Is my only choice changing the throttle as well? Thank you very much.

    Agree. That trike likes very nice.

    Trike mod?

    As the trike needs to climb a 15 degree hill and my girl definitely cannot do that with a weak motor. Initially I think a two motors two controllers two batteries set up all of moderate power should do the work. Chain drive is out of the question because bike and trike can't have power system...

    Trike mod?

    But will a two relatively low power motors set up easier on the trike's mechanics?

    Trike mod?

    Just wonder if one can mode trike like this with motors in both rear wheels. http://item.taobao.com/auction/item_detail-0db1-4cc9ae41aa2e14e009a2a9359310e290.htm Any idea? It will be perfect for my woman, who can't ride a bike.

    Thank you Terry. BTW, the eCrazyman hasn't replied my email inquiry on the shipping cost yet. Perhaps the S&H is a big part of the profit?

    Yes, that looks VERY similar to mine. But 1799 EUR? that's US$2600. Mine is just $600. Either the dealer marks up a lot, or they use some very high grade parts on it.

    Dear Terry, I would expect something like this will work, right? Ecrazyman 36V 350W brushless controller (25A max) http://cgi.ebay.com.hk/ws/eBayISAPI.dll?ViewItem&item=300283998807&pt=LH_DefaultDomain_0&hash=item45ea523257&_trksid=p4634.c0.m14.l1262 BTW, right now the bike has an 1:1 PAS...

    The bike is actually quite a good one. I costs me less than US$600 with S&H and everything included. Just that I am asking too much of it. Not its fault. :( I may take some photos of it to share with you before I take it apart for surgery.

    Thank you! thank you! thank you all of you for your replies. Dear KiM: That cyclone kit looks nice and the torque/power seems amazing. And it is cheap too. Sounds a viable option. Stealth factor is a concern though. No form of ebike is legal here...But if there is no other option, I may try the...

    up-rate suggestion for hill climbing

    Thank you Rassy for your response and analysis. That slope, unfortunately, is a 12-15 degree slope. I have checked it (on an iPhone with inclinometer software). Imagine walking up that slope on a hot (95F) and humid (over 90%) summer day. I really want to get rid of my car, or at least...

    Dear all, I have this bike: http://www.unikcycles.com/big_.asp?pid=155 It is a good looking and well built bike. Yet, its motor is too weak. I have a 15 degree slope to climb right in front of my house before I get to the main road. Right now it only has a 250W geared motor which isn't good...
