    BBS02 Yuba Mundo w/thru axle Build

    It looks cool, I'm also building a Yuba from frame. my plan was to use a IGH nexus-3 but the weaker axle in 14mm dropouts has made me re-think it. On top of that getting axle adapters here has been tricky. I emailed Ichi about the hub choice and local Yuba dealer and they both questioned it's...

    Fat bike & Cargo Bike

    I've built and restored half a dozen e-bikes now mostly hub drives front and rear but so far haven't done mid drive or fat bike or Xiongda 2 speed. So I've bought a department store fat bike and am using it for parts with a Yuba Mundo frame and a BBS01. Will swap front end so Yuba has a 3inch...

    2WD Electric Yuba Mundo Build

    Impressed by the detail of this build. I'm looking at putting a Xiongda disc motor in a Mundo frame but was concerned about spreading (cold set) the frame. Your description and jig on p5 is great. I still need a bit wider but am encouraged that it maybe possible.

    2 Speed Xiongda hubmotor

    Forgive me if already asked but topic is 28 pages long. I have an Electra Townie with dropout spacing of 135mm, keen to use one of these Xiongda rear hubs and make a poor mans Townie GO. Problem is the bike has a coaster brake, no v brakes tabs, no disc tabs which suggests the drum brake version...

    Yuba Mundo FAT with BBS02 mid-drive

    Did you get it finished? I've come across the same idea from a different angle. Currently my "goto" bike is an Xtracycle freeradical kit built on a sturdy Norco frame but it's impossible to get spare parts for in my part of the world so the Yuba frame kit stands out. having built a couple FWD...

    new handmade e-bike from Italy

    Nice frame, looks light, puts BBS clear of damage, nice low/centre battery weight distribution. I've ordered a BBS01 350w for a carbon fibre frame 29er MTB I already own. Am concerned mounting a frame battery to only 2 water bottle bolts in carbon fibre might be risky off road? Can you give...

    Cargo bike Xtracycle Bafang conversion build

    I like it, I built an xtracycle with a 250w front hub motor. I was tempted to get a rear and go 2WD but a mid would be even better.

    Do electric bikes save lives?

    Bikes don't kill people. People kill people. Specifically people in cars and trucks kill people on bikes.

    Bikee Tomcat electric mid-drive eDH bike

    Looks GREAT but price needs to come down. I'd rethink the colour also? Fatbike option should be possible

    Longtail conversion done. Managed to get 2 discs on a frame designed for V-brakes. Battery bottle on downtube, controller attached to old brake bosses. Also dropped granny chainwheel to fit PAS.

    Bakfiets and mid drive - workcycle long with Bafang 8fun

    The new Douze cycles look interesting. Comes in 2 pieces, 3 lengths and BBS02 may fit above rather than below? http://www.douze-cycles.com/en/

    Contemplating Mid-Drive build

    I love a good 'cycle truck'. Although it may look nerdy those bikes with a straight steel bar forming main frame, front rack and back rack would be very strong.

    Bakfiets and mid drive - workcycle long with Bafang 8fun

    Haven't done it but motor will be low. Mock it up first to see if you're happy. Most conversions I've seen replace 20" wheel with a hub motor adding disc brake at same time. That'd require a weld but steel fork is made for it. The next bike I'd like to acquire is the Bullit and of course it'd be...

    All Wheel Drive AWD - different wheel sizing

    Thanks again for the well thought out replies. Having used the internet since '94 I'm still amazed and delighted that folks take the time to share and answer the Q's of strangers in other countries. I'm going to get the 24" rear MXUS and start experimenting. Fortunately I have some time before...

    All Wheel Drive AWD - different wheel sizing

    My current rig has a MXUS motor upfront on 26" wheel. It also has a xtracycle freeradical sub frame extending the wheelbase at rear making it a cargo bike. As such it's tempting to take heavier loads. I'm considering swapping rear wheel for another MXUS motor and running it all with a single...

    Pedal Assist Sensors

    Thanks d8veh. The sensors shown in your link are a great solution and cheap.

    Pedal Assist Sensors

    This is a problem without an economical solution. I've done a few kits now that all come with PAS sensor and it inevitably requires a longer BB axle or a single chainwheel or both. A simple split ring version of the PAS would be good also or a cheap version of thun BB that works universally. The...

    Longtail Electric MXUS kit on Repco Sirocco

    So it's finished. Time has evaporated with kids in the house. I've abandoned the longtail for now but ended up doing following to finish off. -replaced stem with higher longer stem for better fit and compensating for no suspension. -replaced triple chainwheel with a single and removed front...

    Longtail Electric MXUS kit on Repco Sirocco

    My weekend project was starting a new electric bike. Not as easy as I thought but pretty straightforward. It's a work in progress. Donor bike is a Repco Sirocco. It's actually my mums bike but it's been collecting dust for 5years. A friend bought back a MXUS kit from China for use on another...

    Framebuilder with interest in e-bikes and questions

    If starting from scratch I'd mount 2 bottle batteries vertically behind seat tube. This will naturally lengthen wheelbase and centre the mass. If you want it for errands and to carry cargo use small diameter wheels and incorporate low racks/baskets over front and back. Think a cross between...

    Help identify hub motor brand

    I tapped 3 threads into steel frame seat tube. And then bolted the battery frame onto bike. Also grinded off some unused mounts so that controller could be repositioned on chainstay bridge. Have since got an alloy pannier and rear basket. The overvolting melted 24v headlight so I put a better...
