This is my first thread, and it got started talking on another thread, (viewtopic.php?f=6&t=33290
) where i had spotted an awesome bike that ran exactly how i had dreamed my bike would run one day.. In fact his bike is better than what i had hoped any bike of mine would be, but we have to have goals right?
Anyway, I didn't want to hijack the other bikes thread with all my questions, so decided to continue my questions in this new thread. Here is wher i left off.
the 8T was exactly what i had in mind, but recently had thought of getting the 12 fet controller. I definitely wouldn't need anymore grunt than what your bike could do, but thought to get the 12 fet in case i decided i wanted to build something bigger down the track. (would be a different bike than my current)
My mind has been bouncing back and forth between the the kit you mentioned, and cell_man's 1000w kit which had the 12 fet..http://www.emissions-free.com/catalog/i24.html
Which ever kit i went with though, i was definitely going to ask for the 8T winding, as its a great allrounder from what i have read and it already has a top speed faster than i would dare to go on my bike. (the default for the 1000w kit was a 6T). So the bigger controller was going to be more than i needed for now but seemed not much more money. The other thing that i was keen on was this 3 speed switch and Cycle Analyst connector. It didnt mention those on the 500W kits even though i think you can get it for any of those controllers.
The 35kph speed with a bit of pedal is exactly what i would be using the bike for at the moment.. The bike I got is only a Giant Rincon about 5 years old. It has an alloy frame, so would definitely have to make some steel torque arms.. It did come out with cable disk brakes though, but has an 8 gear cassette on the back. I think i will need to change that to a 7 or 5 gear rear to fit with the motor and may need to make a mod similar to yours to fit the caliper from rubbing the motor. Either that or look into a thinner caliper.
At this stage, I am certain i want the 8T motor, unsure between the 9 or 12 fet controller. I am sure both are plenty for me, but its that "future proof" thought in my head that is confusing me. They are not much different in price, and i wonder if i use the 12 fet, can i program the controller to not use the higher current, thus getting more run out of a battery charge more like the 9 fet would... Or even use that 3 speed switch to force only partial throttle.. That way i can have the bike i want now, but still have the larger current controller at hand if i ever decide i want to build bigger later. Any idea if a 12 fet controller can be used as though it was a 9, just by programming it?
There seems to be a few batteries to choose from and i certainly need to read more about them. You happy with the Ping? I have heard awesome comments about the Ping batteries on this forum. I also need to consider shipping charges too. Might be cheaper to just get the batteries from cell_man and combine the shipping cost with my kit, than to get the battery from Ping. Not sure, and don't know which of the two battery types suits my needs better. From what i have read, for commuting the ping battery is safer, and will live for longer than lipo (especially for an unexperienced person like me). For racing (which i am not doing) i read that lipo is better for more hard bursts of power. Something about 2C and 30C i read. If what i read is right, then the Ping might be the one for me. I want to commute, and don't want to burn my house down while charging.. I am not sure about the A123 ones from cell_man yet.. need to read more about those batteries too as many people use and like them too. This forum is the beez neez for all this info though.. I just need more time to read it. Heaps more time.. Shoulda listened to my teacher years ago when they taught speed reading.. lol.
Sorry to write all this on your thread.. I really should move this to its own, so as to not side track from the real spotlight, which is your fiberglassed beast.
I will make my first thread now.
