Time for another ebike build! 8) Didn't have a build for the 2011 summer season due to many life changes, but it's time to get back in the saddle again. This summer I'm opting to try and keep things more simple compared to previous Rube Goldberg experimental builds.

New bike will be a cheapo Costco North Rock XC6. Nice looking triangle is what caught my eye... and the price. And front shock (even if it's a sucky one). And disc brakes. Etc. Will be the most modern bike I've ever ridden that's for sure. Hah.

Ordered 26 Makita packs from Doc. After looking at various other battery options I kept coming back to my beloved konions. I live in an apartment again so opted out of Lipo, but it was tempting. Having mistakenly taken konions to 4.35v+ before without incident I don't trust myself with Lipo. Ha! 18s10p will be the build this time. Going to mount in the big North Rock triangle. Should fit a peach. I already have a 75.6v charger. Tab welded with my little 1.5 farad 16v welder and nickel stripping just like years past. Works well enough. Will be running a measly 2-2.5C full bore with a likely 50% DoD most days. Should help cycle life etc.
Got a little Lyen 9fet from ambroseliao (thanks!) that I plan to start with. Looking forward to playing with the programming. Will be running it ~72v and 30A max most of the time. Should be fine with the 4310s in there. From what I've read the little 9fets run efficiently and stay pretty cool. We'll see. Price was right and it has the Cycle Analyst connector so that's cool too.
Going to start with a rear 26" 2810 from MethTek. I run 2kw+ for 15-18 minutes sustained climbing up to work and I'm not convinced that a 2810 will be up to that, but I'm tired of the uber heavy Clytes I've run in the past. If it's too close I can opt to aircool drilled or try the newer oil bath treatment others are doing. Hoping to sustain at least 16-20mph up the 8-10% slopes with minimal pedal assist. We'll see. I've got a quote in to Cell Man for a 12T MAC, but have yet to hear back from him. If the 2810 doesn't cut it I'll slap it on the girlfriend's bike.
More to come... it's just beginning again...
