Thanks Alan for you suggestions, In fact I have a head rest, and besides supporting my head it help me to realize when I am not relax on the bike , because when I am "stress" my head is not on the head rest. Regarding the cadence, I am improving I realized that I was using the smaller sprockets than I think base on the position on the bar end shifter. I thought I was on bigger sprockets that really was. Now I just try to spin fast and don't look at the sprocket.

Nice set up! Regarding your max rpm, could it be that during a short acceleration you get a "peak" value for rpm which is giving an unreal value for rpm? I am guessing... I have talking with tongxin sells and they told me you can get a pedal sensor + throttle or pedal sensor + display with buttons. With the throttle there is an "auto" function available so after 8 seconds enters in autopilot and you don have to hang the throttle anymore. The display with buttons shows the battery status and you can set the speed to 6 different positions. I think the display is the better option. ( Also with brake sensor to stop the motor if you are braking) Pd. I am getting used to pedal with the recumbent , at first my legs "hurt" when I climbed.. but everyday is better, i am improving...

Thats interesting.. If this two speed are the max torque and max efficiency will be great! As you can see in stoke monkey official website this is the "sweet" zone , where you want to operate you motor ( the curves for tonxgin may be little different but the concept is the same) http://clevercycles.com/blog/images/powereffsweet.png Clever Cycles » Blog Archive » Motors and bicycles i will contact tongxing to see how the controller can work. i think the best way will be a pedelec sensor combine with a throttle that remain in the position you set it. That combine with a rpm computer (as you are planing) so you can tune it. On the other hand if you set correctly your sprocket / chainring so your usual cadence meets the RPM of the motor on the sweet zone, you haven't got to control to much your throtle, isn`t it?

I am not sure, If you get the pedal sensor , it would only work when you pedal ( that´s fine). But if you haven´t got a throtle how are the rpm of the motor set? You would like it run always close to highest efficiency point but how is this achieve?

No I am in spain

Yes this is what i am thinking and in this shop, i have contact them before. They also have the controller and diferent options: throtle, throtle+pedelec. Etc. They told me you can have pedelec and throtle both together. So it only works when you are pedaling and you can set the rate of power with the throtle. I am not sure what to get. I want to be able to use it with motor off. And with motor on, i will prefer the motor run "automatically" without much "human" iteration. I supposed in any case I also have to bought a brake-sensor so inmetiatelly stop when you brake. Yes I have a stree machine gt ( steel) bought it two days ago. My plans are to stoke monkey. I want to get used to it first, it is my first bent and I am impress how confortable and easy to ride is!!

I didn't know there is a 175 rpm version , I only know the 190 rpm ( supposed to suit 26" in) and the 260 rpm to suit 20''. I supposed yours is suit for 28" wheels... What sprocket / chainring combination are you running? Are you running their controller ? I want to order a hub motor from them but not sure about what accesories to get: hub 36V /190 rpm with disk brake + controller + Thumb Throttle Does the pedelec sensor makes sense in this configuration? pd. I have also got a streemachine ( just get it yesterday)

Hello kitchenman, I have been reading all the post great job! First which tongxing rpm have you got ?, i supposed the 190RPM which will be better to get the reduction to 70 rpm. I have some doubts: You attached that aluminium piece to the hole of the spokes and then the sprocket to this aluminum pieces because your hub hasn't got disc mounts isnt it? If you mount a fixed sprocket in the disc mount of the hub, would this works for freewheeling ( i mean pedal with no motor drag when motor swich off?) when you dont want electric assistance and the motor is switch off, when you pedal the motor hub is spinning but thanks to the inside freewheel of tongxin motor there is no drag coming form the motor, isn`t it? In case the motor was direct drive, you couldn`t have this configuration, cos you will have the motor drag isn`t it? I.e. the stoke monkey seem to be a direct drive motor and they have mountend a freewheel sprocket to have freewheel between motor and chain when motor not working and you are pedaling. Then 0 drag from motor when switch off , Am I right??
