This is going to be a bit of a hybrid thread, in that it is both a build thread and a review thread for a motor/controller kti from Fusin (as described in this thread here:
The actual kit hasn't arrived yet (is at Customs in San Francisco as of noon PST on 5-17-12), but is expected by beginning of next week at the latest. Once it's here I'll have pictures of the actual parts; until then Louispower has pics posted in the above thread.
The only thing not included with the review kit is a battery pack; I have several kinds I can try with it, but I will probably use RC LiPo because it is small and light and modular, so I can add Ah as needed for range, and start with a small ammo-can 14s2p pack,
for 10Ah, 58.3V fully charged. I will likely also use a Methods' LVC/HVC monitoring system on the packs, and reviewing that here, too, as a secondary function.
The new motor is rated 1000W peak, and is capable of up to 40KPH in a 26" wheel. It has disc brake mounts on the left side, and most importantly it has a cassette spline with internal freewheel built in, instead of the old-style thread-on freewheel. AFAIK it should support up to a 9-speed cassette. Supposed to fit a 135mm dropout.
The controller is PAS capable, and there are several modes it can use the motor in. Per Louispower at Fusin:
We limit the controller current under 18A, with that when the intput power is 850w(17.71A), the measured output power is 675W, efficiency is about 80%. In the test video the battery's max discharge current is 14.9A, the analyst shows 720w at most, means the output power is 576w.
There is a handlebar display for speedo, battery level, power level (presumably how much current or wattage is being drawn by the motor), time (dunno yet if its' a clock or a trip-time counter, or what), error codes, etc. SHould be interesting to see this, as it would be a great improvement in information availability during a ride from what is supplied by most manufacturers. Probably not as much info as a Cycle Analyst can give, but it should be enough for most people's purposes.
Since Fusin used Shimano integrated brake/shifter levers in their testing, I am also going to do that, as I have a set I got a while back for a couple bucks at BuildABike off their used parts rack. Fusin has ebrake sensors intended to mount on existing brakes, rather than having to use their own brake levers. This should be a really nice feature, as it's been problematic on various people's builds when they have hydraulic brakes or whtnot and can't easily use the supplied ebrake levers form whatever kit they got.
I have a number of possible bikes I coudl put it on. DayGlo Avenger (with the older style front Fusin) is one candidate, but I would have to take off the cargo pod and rack to do it, as I want access to the motor for various things during testing, including any possible roadside repairs I might need to make (unlikely, but hey, it's me and it happens a lot so I figure I should be prepared ).
Nishik-E is also possible, but it is what I want to try a very light chain drive in so it will likely leave it alone for now.
The Velcro Eclipse doesnt' have anything on it right now, but it also is not fully together. Same for the Schwinn Sierra. If I have to put a bike together, I might as well do it with a full-suspension bike, which will be the first one I have ever had to ride. Should make the commute nicer on the roads around here.
So...I'll be starting out with this Diamondback Coil.
The frame, cranks, and chain all came together from Mdd0127 a few months ago, and I have been pondering how I might use it. It's aluminum, but the rear swingarm is steel. It doesn't have disc brake mounts there yet, but being steel it's easy to add them. Plus I can also use rim brakes, if the rim the motor comes in is made for that (probably). Then I will have dual rear brakes--helpful since I won't have any regen braking with this motor, as it is a geared with internal freewheel. Placeholder wheel for figuring out settings and geometry is the rear from the Schwinn Sierra.
The fork is an old 2005-ish Manitou Skareb I got on a mishmash-parts bike a while back, mostly made of worn-out junk but the frame was ok (it is now part of my newest bike-in-progress to repalce CrazyBike2 eventually), and the fork could use a rebuild but it does appear to operate almost normally. I need to re-air the shock up , as it has leaked since I last did so. It only has about 20-30mm travel left afer I get on the bike right now, but it shoudl be 100mm I think. I need to re-find my PDF manual I found for it and re-set it up. If I can't get it to work, I can use a Suntour M2000 fork I got for a few bucks at BuildABike aroudn the same time I got those shifter/brake controls--it is identical to one Mdd0127 gave me that is now on CrazyBike2, and that I welded a disc-brake mount to. But I'd rather try this one out first, as I have yet to use it on a bike, and am curious if I can make it work.
The wheel I want to use is a 24", whcih means it wont' work with the rim brakes
so I will need to make a disc-caliper-mounting bracket. it has the rear-post holes for one, just not the bracket itself, and the regular ISO on'es require a side-facing mount hole tab this one doesn't have. Shouldn't be too tough, but I have to find the material to do it and then the time.
There isn't much clearance for the disc, either.
It's just a 160mm rotor, originaly from AussieJester's custom trike. I have a 180, too, but its' not ISO holes, so I'd have to drill/file them out like I did with the one on CrazyBike2. Already too much work to do on this bike, so I'll pass for now. I still have to find mounting bolts for the disc, too.
The steerer is a little short for this headtube, but it might be ok. We'll see, after I actually get everything moutned tight and all. At least the clamping part of the stem is below the top edge of the tube. I have a cap to screw into it somewhere, but haven't found it yet. (it has taken several days of spare moments to get even this much stuff located and together!).
Handlebars came off a Specialized bike with a cracked seatstay--an ex-coworker abandoned the bike here more than a couple of years ago, and I have not heard from him since then; so assuming I am never going to, and that he didnt' really care about the bike enough to even pick it up, it's getting parted out. I wanted to use the adjustable stem, too, but it is for a threaded headset. I may still be able to use it on here, but I have to get the little star-inset out of the steerer first; not entirely sure I can. Until then, I'll just use this regular stem from Goodwill. Can't remember the price; it's worn off the tag.
Cassette will come off an old Suntour hub, unless it doesn't fit the splines or lockring threads. It's a 7-speed.
IF it won't fit I'l luse the 8 or 9 speed off the SPecialized
I gotta find the right diameter seatpost, though, cuz all the ones I ran across so far are way too small or way too big.
I also wanna change the crankset, partly cuz it's heavy steel, and I want to take as much weight off the bike as I can since I am adding the ebike stuff. Partly cuz I prefer the ovoid rings as they help my knees a little compared to round ones. One hope is to use this bike for light-rail trips down to Aerican Foods, out in Mesa, as well as a friend's house that is out that way. So it needs to be light enough for me to lift and stuff if necessary. Sure, I can just pedal-bike there, but it'd be nice to have the opton to ride further than my knees allow...or carry a little cargo back with me besides a single small backpack-on-a-rack.
So I have these old aluminum cranks and chainrings, but I have to find mounting botls to put them together. They didnt' come with any, in a junk box from someone else.
For the possibility of cargo, I have some old baskets for front and rear I used to use on what later became DayGlo Avenger. The rear ones will have to be modified to work on a full-suspension bike, so they mount to the frame and not hte dropouts, so those won't go on there at first. Dunno where they are so no poics yet.
That's all for now, until I get more done on the bike or the kit arrives.
