    Mostly working CA3-DP

    ** SOLD ** Speedometer stopped working. This is the second time this has happened with my setup and I don't know why, but it's easier to just buy a new one than try to figure it out. Everything else works fine as far as I know. Plug is obviously modified and will need to be remade. No...

    Low Speed, High Torque Hub Motor?

    I was recently looking for a low speed hub motor and found Ozo (in France I think) has a variety of low Kv DD motors. Might be useful.... https://ozo-electric.com/en/27-brushless-bldc-motors?p=3

    Shop Cleaning Free Pile!

    **UPDATE** Cycle Analyst, charger, E-Moto controller, and Golden Motor parts are taken Located in Seattle, don't really want to deal with shipping, so locals get priority. QS205 axle Cycle Analyst. Can't remember the condition of this one. Obviously the leads have been totally hacked. I...

    Tangent Ascent 40:1 3210 kit $1200

    I bought this from another user on Endless Sphere in 2016, installed it on one of my bicycles, and rode it for less than 100 miles. The bike has sat in my shop ever since then. This was my first try at mid drives, and it turns out I just don't like them. I prefer the smooth, silent, instant...

    GMAC 10T CA v.3 speedometer readings off by a lot

    I have a weird variation on this problem. Phaserunner with MT plug using a L1019 adapter harness to connect to a GMAC. The harness has a separate 2 pin JST connector with white and grey wires at the controller end, but there is nowhere to plug it in. I'm thinking I just need to cut the speedo...

    Custom salt water electric cargo trike

    I'm happy to hear this advice, since I'm most familiar with and comfortable working on hub motors. I think a very small one will suffice for this since the additional gear reduction to the rear wheel will give us plenty of torque. This is exactly what I'm thinking, too. Belts will be harder...

    Custom salt water electric cargo trike

    I got my friend who used to work as an engineer at an aluminum boat manufacturer to give me some advice. According to him, galvanic corrosion will not be that big of an issue since my vehicle won't actually be submerged, but general corrosion due to salty air will definitely be an issue. 6xxx...

    Custom salt water electric cargo trike

    Yeah, I think that's probably what I'll do. 3 speed Sturmey Archer, and fat tires.

    Custom salt water electric cargo trike

    This is making me think maybe I should consider making the frame and everything from stainless. I don't relish the idea of doing all my cutting and welding in stainless, but I can get tube and shapes in 316 from the same supplier. I can get stainless bearings with stainless housings, stainless...

    Custom salt water electric cargo trike

    I have a customer asking for a custom trike project and would love to crowd source some ideas about how to proceed. This trike will be used for maintaining and harvesting oysters in a salt water environment. It will be ridden on sand flats that are exposed when the tide goes out, so not...

    Another "stealth bomber" build.

    If it's a steel steerer tube, the welded extension should work. I've done it a few times myself. Turn a tight fitting internal sleeve to bridge the connection between the old piece and the new piece. That will help keep it in alignment. Clamp it in V-blocks for welding if you have them...

    Another "stealth bomber" build.

    It looks like that bike and fork should take a standard 1 1/8" threadless headset. They are very common. There's no reason it should take a month to get it. However, it also looks like the steerer tube on your used fork is too short, as you suspected. If you're really ambitious you might be...

    Single Sided Hubmotor Mount Design, Integrated Torque Transfer

    Amberwolf- sorry you asked me about this a while ago and I didn't get around to reading it thoroughly until now. I think I understand all the features, and I would say it's technically possible, but pretty difficult to do well, especially DIY-style. There are a few major tripping points. One...

    what motorcycle tire fits a 16" bike wheel?

    Unfortunately, I don't think any moto tire will fit. As far as I know, 16" moto -> 20" bicycle is the only magic crossover size.

    Custom high power full suspension aluminum cargo bike

    Aaron can do cleaning and oil changes, and replace shell components, but cannot service the guts. As far as I know, even Cycle Monkey sends them back to Germany for internal repairs. I'm not even sure they'd be willing to work on mine since we drilled the flanges for a 48 spoke wheel. This...

    Custom high power full suspension aluminum cargo bike

    Yes, the very same one! It's really old, and it now has periodic skipping in 6 of the speeds, but I've been too cheap to send it back to Cycle Monkey / Rohloff for a rebuild. Yes, that's definitely a drawback, along with every other modern mid-drive production frame. Maybe someday there will...

    Custom high power full suspension aluminum cargo bike

    I've been riding my existing cargo bike/tandem for years now, upgrading it piece by piece, and I'm ready for the next iteration, starting from the ground up. Here's my current feature/part list Custom 6061 aluminum frame machined and welded by me, heat treated at another local shop. Mid-tail...

    55.2kw bicycle

    Kelly likes to name their controllers after the phase amps, not the battery amps. 60 kW is never going to happen with that setup, because it will only output the maximum 700 amps at low speed (low voltage). To calculate the maximum power of your bike you need to use battery amps (the input...

    Building a solid rim for my QS205

    Well it's my shop so I get to waste my time as I see fit. :D But yeah, you're right, it would be very expensive if I were doing it for a customer.

    Accelerated Systems ASI BAC 4000 & BAC 8000 FOC BT Controllers

    Unfortunately, I have to report the same experience. I have had good experiences purchasing from Alan at ERT in the past, so my hope is that there's some reasonable explanation for this delay, but I'm starting to get frustrated with the weekly unfulfilled promises. I can understand if there's...

    Building a solid rim for my QS205

    You may notice that I've also ditched the stock QS axle for a custom one to match my custom-built fork. I did this operation for my first QS motor, so this one needs to match. I took some photos this time. Photo 1: Stock and custom axle side-by-side Photo 2: Test fit in my fork Photo 3...

    Building a solid rim for my QS205

    Well, I did it. It was interesting to discover that the spoke holes were very much not in a perfect circle. I ended up filing out our beautifully precise CNC-machined rim holes every which way to match the wonky spoke hole drilling on the motor. Photo 1: Spoke holes threaded to M5 Photo...

    Regen braking - no disc brake -> Possible??

    I have a similar setup and do at least 80% of my braking with the variable regen, and the other 20% with my front brake. It's very effective. However, I wouldn't want to be without a rear brake just as a redundant safety feature in case something goes wrong with the regen or my front brake...

    Kelly Phase Amps to Battery Amps

    My QS 205 V3 50H 5T runs awesome with an unlocked Sabvoton 72150 (200 battery A, 450 phase A) even though QS calls it a 3 kW motor with maximum phase amps of 244. I can watch my power rise to over 14 kW briefly on my Cycle Analyst. Even after going up a big hill maintaining 7-8 kW, the motor...

    Kelly Phase Amps to Battery Amps

    Kebekua- That's very interesting information. Thanks sharing your experience about how the numbers equate to real world performance!
