    Compact Bamboo Long-John Cargo E-bike

    I was really concerned that remote steering involved critical geometry consideration, but I was overthinking it. For my build I sourced a local used fork in ebay, and sectioned and MIG welded a length of new steel tubing between the upper and lower portions of the steerer. I cut off the fork...

    Yeah, if you ever cut through a double or triple butted steel triangle and see how scary thin it is, it makes you appreciate the skill needed to build steel frames.

    Compact Bamboo Long-John Cargo E-bike

    ZeroEm - I'd say bamboo is probably the same or heavier than most comparable shaped frames. When you have no experience doing successive builds or destructive testing, you tend to overbuild your lugs. Same problem if you built your first carbon fiber frame by hand without molds and intimate...

    Compact Bamboo Long-John Cargo E-bike

    Much thanks to James at the Bamboo Bicycle Club. Here are some shots of my finished Compact Bamboo Long-John Cargo E-Bike. I designed it on SketchUp. It's inspired by a German Muli design. It has a 1000W mid-drive Bafang motor, 2 used 491Wh e-scooter batteries, located in a homemade battery box...

    16"+ Speed sensor on Bafang 750 BBS02 = top speed

    Answering my own question here. The Eggrider will override an old BBS02 controller's speed limiter.

    Eggrider won't display excessive speeds?

    Is there a known issue with Eggrider V2 where speed displayed rolls over after you exceed 29+ mph? Just about to start my maiden voyage on new build and testing it out on jackstand (trike), I can see it go to higher speeds than 29 but display shows teens and 20s as if 18 is 38, and 20 is 40...

    GreenSpeed GLR Trike w/BBS02

    Even a top quality chain means you have to pay 3x. But it will last 3x longer, so there's that. I went with KMC X10 with the Ti-N gold treatment. This is why I can't afford new spokes :lol: I did restrain myself from spending the extra on the 10XL. Also note to all trike owners. Keep your...

    GreenSpeed GLR Trike w/BBS02

    Agreed that reusing old bent spokes seemed like false economy. I now work for a non-profit and this bike has no specific need in my life so it was an extreme use of discretionary income, my bid to prove to myself that you can grocery shop 18 miles away from your home with a trike. My work is...

    bbs02 - what size chainring for my commuter?

    Thanks for the extensive report back, Kim. Most people aren't interested in the high speed travel unless they are using the bike for utility on long open road travel. Then it becomes a big advantage. With most bikes you start hitting that aero wall, which is why I think many people say there...

    GreenSpeed GLR Trike w/BBS02

    Two spokes were broken inside their nipples on this wheel These hubs are probably very hard to replace, so I decided to try to refinish them, low-budget style Bearings were pretty shot This was a gamble. I could grind the plastic coating off these, but that could leave scratches & waves...

    GreenSpeed GLR Trike w/BBS02

    Bringing Greenspeed home - at this point I still thought I bought a GTX from 2004(ish). Prev. owner didn't know model or year. Started to realize it's actually a more rare 2002 GLR and that it has the 7 x 3 internal gear hub but with a 9 speed cassette fitted Even race trikes are tough to...

    16"+ Speed sensor on Bafang 750 BBS02 = top speed

    Maybe I'm misunderstanding how far the software/programming cable has come. Is there better software than Bafang Configuration Tool V2 to use that'll easily unlock the 40kph limit?
