    From Concept to Prototype: Ultra-Light Ebike Kit for Road Bikes Now in Development!

    kindernay like hub-shell would be great to be able to service the motor and easy-er building wheels. Also how are you going to include a torque arm/ non turn washer like thing to the hub? Build in rotation sensor or pressure sensor?

    stompandgo's Cannondale Tesoro Neo X Speed build

    looks great indeed. If you are worried on the contacts... loads of bikes here lost the rubber connector protector and still have to see a fault resulting from it. You could also use one the 4047025643092 to cover the battery connector pins. And just do not forget to take of the external...

    Dreaded Error code 500 after 18000+km. Can I just swap a motor?

    A Bosch dealer could reprogramme the BDU based on the image which would come from the old BDU if they could read out the system. (I ve done this a few times to many handling dealer support) Ir if the system is entirely not connecting to the bosch pc interface the brand send an image of the...

    Specialized Como 3 - Rear brake doesn't work anymore.

    Rather easy video, depending on the caliper bleedport you would need a different bleed kit. Starting point could be https://www.mantel.com/it/kit-di-spurgo-shimano-bleedingkit-tl-br And yes, if the bolt was turned into the caliper with force in crostreading the bolt in the caliper this could be...

    Specialized Como 3 - Rear brake doesn't work anymore.

    Did you actually see fluid leaking from the bike/brake/calliper/lever? If so, you could post a picture so we could "see" what you see. Also when brakepads are worn and you keep riding you could potentially wear out the brakepad carrier and push the plunger out to far so that the fluid is...

    What is this part ?

    Ok, I did not propose to hose down the belt. For some reason when bikes in the field (either visited by the mobile mechanics or via a dealer) cannot be diagnosed/repaired these bikes in the end arrive at my desk to find and repair the issue in it. For this type of noise the fastest way to find...

    Vado SL 2 Alloy version released

    Indeed in North and South Holland (Amsterdam, Rotterdam, den Haag etc) have rather good cycle paths. In the rest of The Netherlands the story can be a bit different. Around Amersfoort there a lots of older cycling lanes/paths with crappy asphalt, bricks and in some regions cobble stones...

    Vado SL 2 Alloy version released

    indeed same mount. The handlebar bags on the Tern's do get a good whack when riding on unpaved roads, the swing "a bit" up and down with the 20" wheels, never lost one. Maps are unreadable in those conditions... Alpkit does have a EU shop now so shipping from them would be easier these days.

    What is this part ?

    Either reset the caliper compared to the rotor or find the spot that is out of true and bend it gently (with a clean tool) so it doesnt run into the brake pad. very clean Bahco does the same job, and be gently

    Vado SL 2 Alloy version released

    that one from Ortlieb? BTW, the EN rating is for the rack. I've seen a lot of front racks on the test jig, not many tend to survive these test. And indeed moving the handle bar mount from one to another bike is not a 2 minute job. So that's the reason we have a few of them on different bikes.
