With the Gold Rush how does the motor driving the crank feel? I'm most interested in any riding problems or adaptations powering the crank has caused.
I'm interested in this because I'm making my own e-bike soon. Plan is to use a Crystalyte 408 project motor and a custom made bracket to drive the crank on my old commuter mountain bike Stokemonkey style. Planning on making it "legal" (pedals, <20mph, <750w) so it'll be geared for a slow 79rpm max motor driven crank rpm. (I like crusing at low cadences. need to measure how low sometime...) Going off ebikes.ca simulator this gearing puts max power at ~50-60rpm crank speed, which I think is about my favorite cruising cadence.
Sincerely,
Lawson

I have been riding my 2007 vintage Mongoose-Recumbent conversion with it's 450 watt Currie motor for over a year now, and regulary see speeds in the 28MPH range. I just finished building a second electric recumbent bike, this one with a Cyclone 500 watt motor. Riding position is about the same, and I'm using the same battery, but this motor seems to poop out at about 23 MPH. I'm now questioning it's efficiency. Does it need to be broken in?
Thanks,

Hi Pete,
I have 3 gears left above the one that seems most efficient for 23MPH. I geared it for 30MPH at max RPM using my recumbent bike simulator:

Not sure on the current. I guess I need to buy a Cycle Analyst.
What kind of top speeds do you see with the Cyclone on flat pavement?
-Warren.

G'day Warren,
I am running the 650w Cyclone on a Greenspeed trike. My gearing is setup for 40 mph at 3600rpm but on the flat I can't reach that because of a combination of back EMF and (I think) a lack of amp limmiting in the controller. Once the motor gets past about 2500 rpm (ish) the wattage tails off even with the throttle held wide open. I think my setup is behaving almost identically to yours in that I have another 4 gears to go but it is very difficult to make use of them with my current battery (Ping) . If I grab the next gear and keep holding WOT I will usually pop the BMS because in such a tall gear the motor can't get up to the speeds where back EMF plays a major role in limmiting current, before the BMS pops. I can feather the throttle by watching the Cycle Analyist but it only takes a few degree's of movement to go from 150w to 700w and at those speeds I really need to be watching out for cars that want to squash me.
I can push along at 25mph no pedalling and on the flats, quite comfortably. I can go faster but I don't enjoy concentrating on the Cycle Analyist, I would rather be enjoying the scenery. I also much prefer to be pedalling anyway as I can now hold 35mph on the flats without pushing too hard which is such a buzz when you are that low to the ground.
I am thinking of getting a 36v20 Ping to see if that makes much of a difference to the amp draw. I also need to setup my Cycle Analyist to current limmit which should make things a lot easier at high speed.

Hi Pete,
If the Cyclone controllers are prone to back EMF, then we should just be able to add add a couple big capacitors to quiet that down. I know I have some big old caps, but I'm not sure of the voltage rating.
Wow it's been a long time since my EE classes. Can I string a couple in series to get the same capacitance but at higher voltage?
