    RST Renegade Leak

    Hello, I have a bike with an RST Renegade fork. Recently I noticed there seems to be some fluid slowly seeping out from near the rebound adjust at the bottom of the fork. The adjuster is not turning all that easily either. I can't seem to find a ton online about these forks. Any thoughts on...

    M600 City/Touring Bike?

    Looking to custom build a bike primarily for local use, but also some touring. Been throwing around the M500/M510 and M600 and have been leaning towards the M600 because we want something that can handle hills well and it has the higher 45kmh limit (I believe 500/510 top off at 25). With this...

    Reselling Alibaba Bikes

    This is more of a dream than a reality, at this point, but it's been something I've been curious about the answer to. If I were to ever customize some bikes on Alibaba and resell in the US, what kind of liability do I have in case of a defect (ie a battery burning up)? I know that's a loaded...

    Bleed Technique

    I've bled Tektro Dorado brakes before and used the method where you put a syringe on the port up by the brake lever and one at the port by the caliper. I had no issues with it. I also used the cup at the top to try to get any little bit of extra air out and again on those brakes, no issues...

    Motor Grease

    Anyone know what kind of grease is in the Das Kit motors? I have over 2k miles on mine and I was going to open it up to just check on it. I want to have some grease handy though for when I do that. I keep seeing things about white lithium as kind of being the basic grease which is kind of...

    KT Torque Imitation - What To Expect?

    Hi, I just put a KT 22a sinewave controller on an ebike. It's working out pretty well. I think I got most or all of the settings right. Seems significantly better than the controller I replaced. I'm trying to figure out what to expect with this "Torque Imitation" aspect of it though. I've only...

    Moscow Light Output

    Anyone know the max wattage light that can be connected to the light output wire on the Moscow (Plus)? The wires look to be wired into the mount directly, so it's likely 48v output, but not sure the max wattage that can be output. I guess the limit would be whatever the wires can handle...

    KT Controller Really Waterproof?

    This may be a really dumb question, but is a KT Waterproof controller, with waterproof connectors, actually waterproof. I'm not talking the connectors. I'm talking the box/circuitry. I am planning an upgrade that I'm doing to an NCM Moscow+. The controller for that bike sits near the bottom...

    Ultra Spinning Noise Normal

    This is probably normal but figured I'd ask. I have a bike with a Bafang Ultra. It only has about 150 miles on it. When I stop pedaling and the assist disengages, I hear a quick faint spinning noise from the motor. This happens every time. It only lasts a second or so and just sounds like a gear...

    Bafang Controller/Display with Das-Kit Motor?

    Has anyone swapped out the display and controller for Bafang? I think the motor connector is the same, just not sure if the pins line up with what Bafang expects? After a few thousand miles, there's a few annoyances I'd like to try to iron out that I think a Bafang setup will solve but I prefer...

    Rack Dimensions

    Hello! We recently purchased a Pace 500 for a family member and he loves it. It got me thinking to check the Aventon site since I'm looking for a rack that will fit my fat bike. I'm wondering if one of the Aventure racks will fit. It looks like there are a few different sizes. Does anyone know...

    Bafang Ultra 750w Limit & Power Consumption

    Hello, New owner of a bike with an Ultra. I read somewhere setting the speed limit to 22mph lowers the power draw to 750w. Did that and it seems to. At least the display maxes out at 750w. What I'm trying to figure out is if that changes the power curve at all too. So, for example, lets say I'm...

    luna charger?

    Has anyone every used the Luna advanced charger on an NCM battery? It charges, but if you set it to stop at 80% it cycles on and off every few seconds once it hits 80%. I don't think this has anything to do with the battery since it can definitely tell what the battery level is if it shuts off...

    Battery Safe?

    I think I'm probably overthinking this, but if there is one thing I want to overthink, it's whether or not a battery is going to catch fire. I ordered a custom build bike from a company in China. They have been REALLY good to work with, super responsive, knowledgable, etc. They also have great...

    Bafang Ultra Recommended Chain

    Hello, I have a custom fat bike with a Bafang Ultra that should be coming in early this fall. I have a hub drive MTB now and read a lot about the drivetrain wear with mid-drive, let alone the higher powered Bafang Ultra powered system. Does anyone have a recommendation for a chain? I typically...

    Dehawk Dorado+ Discharge Rate

    Hi, I have a Moscow+ that's a little more than a year old. I got it with the 16Ah battery. I'm planning on getting a second bike with a Bafang Ultra that uses the same Dorado battery type but the controller is rated at, I believe, 30A, although it might be limited to 25A. The new bike comes...

    Cruiser/Hybrid Conversion Thoughts

    Hi folks. Happy ebiker here. I own an NCM that I am super happy with. Been tweaking it and in doing so decided it would be fun to build an ebike. It would be fun to be able to bike with my girlfriend so I'm building one that is more her style. Here's the scenario: I'm doing this on the cheap...

    Minimum Tire Width

    Well - I see a thread about maximum tire size, so how about one about minimum tire size. The minimum tire size for these rims is 1.5" and 100 PSI. I was looking at picking up some 700x42 lower rolling resistance tires (Continental Contact Plus Travel), which is about 1.65". Does anyone else...

    Designing Battery Cover

    Hello! Well I can't get a ton of info about a neoprene cover to put over the battery for the winter, so I'm designing one myself. I spent a bunch of time trying to figure out the dimensions and made a prototype the other day, cutting out an old sheet which actually fit pretty well. The only...
