Re: How to remove cyclone 3k freewheel?

You need a gear puller for that.

Unscrew little Allen screw that is fixing freewheel bushing/collar to gearbox shaft
Using gear puller, pull freewheel with the bushing off
Unscrew freewheel from bushing (that's a tricky part, need two tongue-and-groove pliers)

Re: Cyclone hall effect connector pinout

I don't have access to my files right now but if my memory serves right, 2 wires are used to pass through "ignition" wire to controller. With ohmmeter, find those two wires that have 0 ohm resistance (measured both ways!). I found one post releated: https://endless-sphere.com/forums/viewtopic.php?p=...

Re: Cyclone freewheel replacement, what are the correct measurements?

If you need motor freewheel, then ACS crossfire. It has standard M30x1 inside thread.

For crank / BB chainring freewheel, get it from Sick Bike Parts:
Ultra Heavy Duty $120
or
Heavy Duty $85

Re: USB powered tail light

Or I assume I could use more LEDs in series? If string has 3 white LED's in series (with resistor) for 12V then 5 red LED's with the same resistor would be safe. Why not just use a 12v adapter and 12v LED lights (or multi-voltage lights) that are commonly available at low prices. Cheap low-powered ...

Re: USB powered tail light

Or use a small red film to cover the glass and turn it into a taillight. Not a good idea as white LED emits very little in red spectrum (it's a blue led with phosphorous coating that converts part of the blue to yellow which in combination appears white to human eye). When replacing white LED's to ...

Snow

From my own experience, snow is another disadvantage to rim brakes. Found out last winter during trail riding (and not on the streets!) that between pulling brake lever and actual braking there can be up to 1 second delay. It creates thin layer of ice to the rim (after each braking), which first has...

Re: Cyclone chain alignment - is it possible to move the sprocket?

Motor freewheel uses aluminum bushing/adapter to mount it onto motor shaft. When have access to a lathe, you could turn bushing's collar thinner from threaded side (thick red line on the picture), so freewheel would screw on further outward on bushing. Either that or loosen the fixing screw and pry ...

Re: LEDs - are COB or SMBs offering the widest operational range in voltage and current?

COB module on Tmall 5730 triplet module on Tmall 5730 version has written "digital constant current chip" but clearly shows two 150ohm resistors (in parallel? that's 75ohm). If those resistors are in parallel, then there's about 30mA draw @ 12VDC. 14,5V will roughly double the current. 10,5V from m...

Designed and milled FET-to-case heat transfer block. FET mounting holes are M3 threaded and placed for each FET separately. Block+FET thickness is about 10mm, so if you add thermal pad and a washer then 10mm M3 screw is just perfect, without danger of protruding to another FET's belly. FET cooler.JP...

Re: Cyclone 3000w problem! need disassembly of specific part

Don't bother, get yourself ACS Crossfire freewheel.
You need a bearing puller to get current one off with it's bushing to gearbox shaft. Getting freewheel off the bushing is trickier but you'd need to do it any case.

What do you think it is the cause of the broken? The low quality of the components, the absence of a rear suspension or something else?
No suspension, high tire pressure and heavy bike (about 35kg: 15kg bicycle, 5kg motor+controller, 15kg battery). Oh, and high speed and bad roads.

Re: new cyclone 3000 w mid-drive kit?

I have a hardtail, about 1400km since conversion (250-300km in winter). I wish I had full suspension, even when riding only streets.
During winter I broke rear axle riding local forest biking/skiing/jogging trail - which had quite smooth, worked up surface.

Re: Converting a Cyclone 3000watt PLANETARY GEAR BOX mid-drive motor to side mount

If not suppose I put a 24T sprocket on the motor shaft and then that connect to the 14T sprocket on the bicycle hub would that affect my torque capability to go up hills drastically? You would have about 1,7 times less torque than in 14/14 setup. I know that sizing is for speed and I am wondering i...

Re: Converting a Cyclone 3000watt PLANETARY GEAR BOX mid-drive motor to side mount

Mounted as seen on picture, it will stick out nearly 150mm to one side. That "side mount" would be doable with less protrusion if motor sits above rear wheel, well behind seatpost to clear rear frame arm. Making mounts to withstand the motor torque is a challenge as the motor will sit too far away f...

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

Any suggestions for replacing, it's out of Digikey stock:
supply cap 270uF 3 565-4018-ND ?
Is ripple current important or are the basic parameters enough (capacitance, voltage and dimensions)?

BTW, ACS770-150B is pretty hard to find from other shops (Digikey stocks 2+k)
