    Sondors changed brakes on new Rockstars.

    Just received my Rockstar. It looks like they changed the brakes. No longer Tektro brakes. No brand name on the new ones. Will have to see how they do once I get a chance to ride in spring.

    New Bike with that gurgling brake noise.

    My new Ride1Up 700 has that weird brake noise on my rear wheel - often described as gurgling or underwater or toilet flushing. Several threads here and elsewhere about the issue with some reporting success changing the pad material - but not really explaining why only some bikes have the issue...

    Problems with ST2S

    I've had an ST1 for a couple of years. I commute on it, and now have around 10K miles on it. Still works fine, but I was interested in the ST2S because I wanted better brakes, better shifting, smart phone connectivity, and better distance. Now having bought an ST2S and ridden it for about a...

    Brake fluid: Mineral Oil

    A picture that @america94 posted showed his new light, but it also showed the brake handle and its fluid reservoir. The label show Mineral Oil. Interesting. Anyone has any insight on maintenance, how do you fill it up, probably using a dropper. Bleeding, probably. Can good quality Olive Oil be...

    2013 and 2014 Izip Dash brakes

    I rode both Dash bikes for 2000 miles each. The brakes were constantly needing adjustment, and noisy. Finally I replaced the stock Shimano brakes with Sram BB7s. No problems, no noise. Very pleased with the result.

    SF Bay Area Maintenance

    Hi All I recently got a Rad City, which has been a lot of fun. However, there are couple things that I think i'd like checked out by a professional. I assembled the bike after it arrived in the box. The back wheel came already attached, to the frame, but I am concerned the disk brake isn't...

    Radwagon Renegerative Braking activates without engaging brakes

    This evening, I was riding down a long gradual hill and halfway down the regenerative brakes engaged which made it really hard to keep a decent speed. I wasn't pressing the brake levers (I even tapped on them a few times, but that didn't help). After I stopped at a light, and started up again...

    Radmini weight and potential issues with removing front wheel

    Hi, I'm considering buying a RadMini, but am concerned about the weight. It is listed as 61 lbs, but I would like to know how much it weighs when both the front and rear carrier racks are removed, the battery is removed, and the front wheel is removed. This would, I think, be the minimum weight...

    20,000 in just over 17 months

    I passed the 20,000 km last Friday on my Xu700 which happened to be bike to work week out here at a few days over 17 months of riding. Some figured I'd break some record for distance on a ebike, but apparently some vacationing Aussies hit 22,000 last week in Europe on their Haibike's. I may...
