The controllers of today have evolved, they need a display as the display is the on/off switch becaue they have various power levels and other features. If you had such a controller it would likely be a one speed only controller and likely low speed . You can use modern controllers and simply...

If the turbo controller is any thing like some of the latter tsdz2 controllers then the OSF may not work on them.

If one has the plunger type read /hall switch that relies on the motor cutting out when the plunger is depressed then one could simply plug one in and leave it positioned somewhere so that you could simply use it as a temporary kill switch . These plunger type switch's are used in the crappy...

Displays depend on where you place them, I make a simple ali bracket up and sit mine on the steerer stem and use the head set bolt to clamp the display. It sits tight to the steerer stem and is out of the way so can't really get damaged. Leaving a bike out in the rain will likely see water...

If you aren't using a throttle and your motor has little in the way of over run then brake sensors aren't required, one does run a chance of a blown controller if a throttle is implemented and then relies on the brakes only. Though a different controller I use KT with my hubs and my Tongsheng...

The Revos friction drive frome Bristol another fairly short lived product, no ,onge rproduced and after approx. four years no longer available. I still have my mk1 model from the fundraiing campaign and it is working well .

130 should be ok if 8.1 is the ratio, one can never be sure what the correct ratio is when listed. AliExp simply lists 10.5 for both rpm's.

I'm not willing to comment other then to say as this is a EAPC/pedelec forum this joker should be on a dedicated e -motor bike forum for high power motorbikes.

A lot of lipo chargers do work like that, esp when they can charge various battery series. My SKYRC dual charge is a 1 - 6 s charger and as you say you have to input the correct series and in my case I can input the Battery AH rating. It won't even consider charging if the series count...

I still wonder when differing voltages are mentioned if even the so called experts don't know or understand the volltage ratings, for instance a charger for a 36v will often have thr 42v max charge rating .

1 - 2% of deleiveries by ebike is a joke number , certainly not a serious effort to combat so called emissions and ano brainer when inclines are to be encountered . Their main are restricted to flat terrain places to be viable. My last DPD local was on drop 182 when he delivered my parcel and...

I have unticked the street power mode and it powers beyond 20mph , If I set the speed limit in the display and the OSF it appears street mode unticked simply over rides the speed limit.

Motor magnet count is 16 and motor reduction ( I think) is 10.5 or 10.667 so gives P1 as 168/170. P1 is criucial for motor performance, I swapped out a Bafang cst & a AKM128C to see which I preferred , both P1's were widely differrent . Forgetting to change the P1 , I couldn't reason why my Q128...

Ben isn't using a dd hub so the count will save if done correctly. P1 isn't just about motor magnet count it also has use the motor reduction rate.

The P1 might not be accurate if the gps speed doesn't match the display speed , it is very easy to adjust the P1 UP/DOWN to get is accurate then there is no guessing.

I haven't dabbled to much with the settings , though have done with the hybrid mode setting of PAS & Torque assist. After a year of using the hybrid mode I then changed to torque assist mode only and find I prefer this setting best out of the two. Though I have changed the four level...
