    2019 16" moped/scooter tire pop-off: which is the most puncture proof?

    Reviving an older thread here- Did anyone try the Schwalbe Moto-X 20x2.35 compared to the rest? I have one on the rear of my edgerunner- I've had no flats, but all the treads are pretty well worn off after about 1000miles. I run a tube with orange sealant in it, and this has actually worked...

    GMAC vs MAC and Infineon vs Phaserunner

    Just thought I would post a quick followup- I ended up doing the GMAC with a phaserunner and a 60v 17.5ah blue battery with a Sempu BB. This is on an edgerunner in a 20" wheel. So far I love it. The drag from the clutchless GMAC isn't bad at all, in spite of the numbers, in a 20" wheel it...

    Safety/protection requirements for 'naked' blue battery

    Thanks- I wrapped it in seran wrap, cut pieces of small foam to cover all 6 sides, then again with seran, then covered it all with gorilla tape. Got stuck in some rain the other day, lots of puddles, all good so far.

    Safety/protection requirements for 'naked' blue battery

    Great thanks- So it's safe to assume that the blue brick packs are not yet waterproofed?

    Safety/protection requirements for 'naked' blue battery

    Hey All- Looking at lots of different posts here on cases and bags for batteries, one thing I haven't been able to find is what sort of general requirements are considered normal for a blue/naked battery. I was thinking about making a frame from aluminum angle, and possible sides with black...

    GMAC vs MAC and Infineon vs Phaserunner

    Ok cool, and yeah I did eat through brake pads on my old commute, which was more through the city. I am planning quad piston brakes on this bike for the larger pads if nothing else... That does make the 9c 212 more interesting to me though, less drag then the gmac, only 4lbs heavier and if it...

    GMAC vs MAC and Infineon vs Phaserunner

    Around 25mph or so, maybe a little faster, but we have less air up here in Denver so that's a little easier than the calculators suggest. I'm not going to loose sleep over +/- 1-2mph though (or +/- a couple lb). My main commute is almost all bike path, so no real stop and go other than about a...

    GMAC vs MAC and Infineon vs Phaserunner

    Hello all- I'm planning a new build on an edgerunner and was hoping for any feedback here. I've pretty much settled on a MAC or GMAC motor and was looking at the Grin kit vs the EM3V kit vs a bit of each. My priorities are relatively lightweight, would like to have ~1500w acceleration...

    q128c @52 volts?

    Do you think the 6T Mac in a 20" wheel would be asking too much for it on a cargo bike? Say maybe 400lbs total at most, and typical more like 320...

    q128c @52 volts?

    Hmm yeah- I had a q128c in my radwagon and I could hold 27-28mph on flat ground and show about 300w from the LCD (06)...that's the bike that got stolen. This was about where it reached max rpm, so you couldn't get more than about 300w into it. It doesn't seem possible that I was putting in...

    q128c @52 volts?

    Hello- I'm planning to do a "bike like" edgerunner build and am debating motor options. I will need to be able to pick it up and get up 1 flight of stairs (had a bike get stolen locked outside). Anyway I would like to get into that ~28mph sweetspot, in a 20" wheel. I was hoping (maybe...

    New "TSDZ2 Torque Sensor Central Motor"

    Looking at doing a build with this motor here in the nearish future, one quick question- If I'm starting a buildup from scratch, what drivetrain would you guys choose? Is there a good IGH for this with wide enough spacing? Or just a 1x10 with derailleur? It seems like something with wider...

    Open a q128c

    The Slcd-6 with a S12S controller. I know everything with the controller and display are fine because they drive the q100h without errors. That looks like a good troubleshooting guide though, once I get the replacement Q128C I'll definitely go through that

    Open a q128c

    Bingo- My bench vise didn't open that big, but I went to a auto mechanic and they got it open easy-peasy. I went ahead and ordered a large bench vise for the future. Unfortunately it seems that the problem with my motor is something other than the wires coming out of the axle. They were a...

    Open a q128c

    Ah so the countersunk pan head screws don't have to come out? I was wondering because you can see the core inside turn with the axle anyway...thanks this technique seems the easiest yet. Do you know off hand is it a M5? I might as well give it a shot at least. Thanks-

    Open a q128c

    There we go! I'm going to try this. Apologies I was just frustrated- it seems like needing access to the inside of these motors is inevitable...plus I miss my bike! In any case I'm going to give this a shot.

    Open a q128c

    Yeah- Yikes this thing is really on there...what a terrible design. My wife's bike has a bafang motor and one of hall sensor solder joints came loose. Easy fix. This thing might just be trash at this point. I tried several different pin wrenches, like the adjustable types that work for...

    Open a q128c

    It looks like I damaged the wires coming out of my q128c. I'm trying to figure out how to open it to replace them, luckily I bought the extra cable kit.... Are there screws under the rotor? I put a little locktite on those and 2 of them are going to be difficult to get off. I took off the 3...

    e-bikes on Colorado Rec Paths?

    No problems here in the Denver metro- I think technically some counties have the 750w limit, but I've never seen anyone checking on that. But 2nd the above advice, LOTs of people out on those paths, I know they are pretty heavily used in Summit County as well, so just be prepared for that...

    Sharing Throttle, Brake and PAS with 2 contrs and 2 bats

    Thanks guys- Apologies it's a little confusing. I'm trying to run 2 controllers (each with it's own battery, LCD and motor) from one throttle, pas and brake sensors and I would like to do it without paralleling the batteries together. After thinking about it, I can probably just add a 2nd PAS...

    cyclocross ebike project

    Just some data points: FYI, I do 12.5 miles in 38 minutes (or a little faster, depending on the bike). My cruising speed is either 22mph or 25mph. My average speed is 20-21 mph including stops. My speeds are much more consistant on an ebike. All with a Q100. I only have to stop about once a...

    cyclocross ebike project

    Sure- My route is about the same, I go through downtown, so there are also 30+ stops, lights and signs in a 10 each way mile commute. What was eye opening for me was when I took my wifes bike one day. Her's has a geared hub motor up front, max speed of about 17mph. Mine stock was a DD motor...

    Sharing Throttle, Brake and PAS with 2 contrs and 2 bats

    Right that makes sense- So can I try to parallel the signal wires, as well as the ground wires, but use only one of the 5V sources? And would this still be OK if the batteries aren't charged to the same level? I guess it might be easier to parallel both batteries together, I'm trying to...
