    torque arm picture thread

    One issue that I have been running into with my clamping torque arms (made a few years ago) is that my fitment was a little bit off so when I cranked the bolt down it bent the torque arm a bit and when I loosened it the metal didn't rebound far enough to easily to get the wheel back out. For my...

    How about a 3D printer section?

    Might want to check on the allowable print time at the library, I can't exactly remember how many hours were allowed at my library but sometime between 1 and 3 hours max.

    Shinko SR241 2.75"x19" and 2.25"x19" - Kingston Ontario Canada - No shipping

    Hi All, Figured I would post this tire here first before trying to sell it on Kijiji, BUT looking for a local buyer as it seems silly to ship a big chunky tire around Canada or the world, for $50.... So if you are close to Kingston Ontario and are interested to meet up then send me a message...

    Motor crystallite HT3525 braking

    Glad you were able to find the issue. 1) When you disconnected the cables and made sure there was no short at that location there was still resistance? and then it started spinning again? That seems strange, was the motor partially seized due to frozen water in the hub? or could there be a bad...

    Motor crystallite HT3525 braking

    No problem, well unfortunately it sounds like one of the mosfets is burnt out in the controller, OR, you have a short in the wires on the controller side. The link I had provided has instructions on checking out the controller mosfets. 2 options - Option 1 - open the controller (after...

    Motor crystallite HT3525 braking

    The motor resistance is most likely caused by shorted phase wires, try unplugging the controller and give the wheel a spin by hand if it spins, the controller most likely has a blown Mosfet, or you have a problem with your wiring to the controller. If it doesn't spin with the controller...

    The Downspout E-bike Battery Case

    Great, I have a long list of items to 3d print, and have also added your end caps onto this list. :) Will look a lot better than my handy man special being a piece of umbrella fabric with a couple zip ties holding it in place. It really was a temporary measure as there was a potential for...

    The Downspout E-bike Battery Case

    Thanks! I was able to fit 4 - Turnigy 6s 5.8 ah packs, 3 in the long down spout and 1 pack piggy backing on the main pack. I had 4 latches 2 per side which allowed me to take the pack off pretty quick in the event something started smoking. Sorry for hijacking the tread :)

    The Downspout E-bike Battery Case

    Looks pretty slick, I have been running the same style downspout along the bottom of the frame (from head set to bottom bracket), it has held up quite well (not huge km's like some on here but 3000 km is a good shake down test). I have mine strapped to an aluminum bracket with all-around in a...

    JZ36V Nine Continent - Pole Pairs and Model

    Well I got some spare time and pulled the motor apart - 46 magnets - so 23 poles. On 36.5 volts with the wheel off the ground I was getting around 48 km/h. I ran a few different 9c motors listed on the Grin motor simulator and found the 2805 seems to line up the best.

    JZ36V Nine Continent - Pole Pairs and Model

    Hi Everyone, I have pulled out an old hub motor from storage and was wondering if someone could confirm the model and pole pairs. It's a front hub motor with JZ36V-500W091218082, from what I could find it is likely 23 pole pairs, but not sure what model it is to determine the RPM/V Thanks...

    Replaced Lyen with Grin controller now runs backwards

    If the wheel runs smoothly with around 2 amps draw with the wheel off the ground, then look at the controller manual, most have a jumper in the wiring harness to change the wheel direction, if it is the phase runner / base runner then you can use the software suite to change direction.

    The Cycle Satiator, universal charger for the enthusiasts

    Hi John, That is my understanding as well, and yes the model number would have been helpful, you are correct it is the 4808. I plan to use it as a 12 volt car battery once everyone few years when its -20c and the battery dies from trying to start the car. Main use will be for my two bikes with...

    The Cycle Satiator, universal charger for the enthusiasts

    I received my Satiator v7 in January 2020, it charges a 12 volt car battery. The side of the Satiator says output - 24/36/48, the manual specifications say 12 - 63 volts. See Justin's post in the below link on June 23 7:13pm https://endless-sphere.com/forums/viewtopic.php?f=14&t=60169&start=75...

    Looking to step-up voltage on a 24 volt Lawn Mower

    Hi Everyone, Looking for some advice from people who have used step-up converters. I purchased a 24 volt lawn mower which was originally powered by lead acid batteries and were at the end of their life. Last year I ran the mower on 20ah of 6s lipo batteries and the mower worked great! I...

    Thank you for all the great information, looking for less fiddly at this point. I will start down the road of youtube videos, may set myself up for a few weeks of watching reviews but at least the field is narrowed. I did watch the Prusa factory video which was pretty neat seeing all the...

    Yes that is correct, wrote my message then realized that I had the rotor and stator reversed and corrected all references but that one. Thanks for setting it straight :thumb:

    Rewiring a Crystalyte HS3540

    Gear puller is pretty slick and glad I bought one from the get go. I think I paid $20. Makes it really easy to push out the shaft from side plate, remove the stator (bolted to dropout) from the rotor (attached to spokes) AND most importantly reinstall the stator into the rotor! The magnets are...
