Hello respected forum!
I've been lurking here for a year or so, reading & getting educated, and this is my first post.
I must begin by saying that the level of involvement by members here, and the feel of the place, is unique, and I value your contribution very much, you keep a wonderful forum, and it benefits so many people who're interested in this field.
I have a build plan made up, and before I put down a considerable amount of money, I'll really appreciate some peer review.
Background: I've been riding for over a year a Gary Fisher hard-tail with a 350W Bafang (running 500W) and 2 packs of LiFePo4 36V 8Ah hooked in parallel, with various mods & installations (soldered shunt, self-made torque arms, watt meter, 2nd battery pack retro-fitted, XT60/deans connectors where needed). It's time to take it a step further
Objective: A high-end bike (DH frame), with a decent & reliable system that can deliver 40-60 KM/h, with short periods (like 2 minutes) of ~70KM/h. Most of the time I'll be cruising ~45KM/h so as not to arouse suspicion, but I'll want that 70 for whenever I have the whole road to myself 8)
My terrain is mostly flat. I plan to use the bicycle as my primary vehicle to work & back. Each way is ~30KM and I can charge at each end.
So here's the recipe:
* Bike: Downhill/Freeride bike with space in the triangle (yet to decide on one, perhaps Felt Redemption) (around 1000$ here).
* Motor: Crystalyte H40 Cruiser from Ilia @ebikessf (great communication, btw). 460$ + 85$ shipping.
* Battery pack: Hook up this LiPo in 4S5P pattern: "ZIPPY Flightmax 3000mAh 6S1P 20C", amounting to 24S 15Ah in total. 588$ + 90$ shipping.
* Controller: LYEN Edition 12 FET 4110 MOSFET Extreme Modder Controller. 129$ + shipping
* Charger: Turnigy 4x6S 400W Lithium Polymer Battery Charger. 124$ + shipping.
* Power supply: Hobbyking PS35 DC Power Supply for Chargers 35A (350W)
* 3-speed switch. 15$
* Cycle Analyst V3 (with the temp control). ~150$
* Wires, Connectors, solder, more tools: ~200$?
The battery pack shall be 24S 15Ah and the controller set to 50A max, which according to ebikes.ca simulator (BIG THANKS for that, a friend and me played with that thing for hours!) should give a 44KM range @50KM/h.
How does this look in general? Anything missing or miscalculated? Appreciate any comment before I put the big buck!
Thanks in advance,
Assaf
