    Cushcore, which rear tire for durability

    I don't understand how cushcore would affect on tire durability. Most problems when installing cushcores that you don't watch the installation video and don't drop the bead correctly. Maxxis and not using levers sound a little internet rumour.

    Bosch BDU4XX electric connectors

    The idea is to extend derestictor's wires so that it could be installed above the motor in seat tube. Currently it's so tightly packed between the motor and rockguard and the wires are exposed on the rockguard holes. The wires have already scratches. Another or default option would be using...

    No power to motor - Purion dead?

    The motor was faulty and was replaced. Bosch gave -50% goodwill price so in total it was 499€ including LBS work. The LBS was once again super with all communication etc 👌 eventhough the bike was not bought from them.

    Would you buy a bike that can't be derestricted ?

    Really? :ROFLMAO: I did that for myself. Easily. Even the idea that I would first buy an expensive emtb and then ride against the 25kmh limit in the forest meanwhile in some other country the very same limitation was 32kmh. That was too much. At the same time I can fully understand why...

    What did you buy your ebike this week?

    Rather use "Heat Shrink Solder Sleeve Crimpless Butt Connectors / 26-10 AWG / Electriduct". The yellow AMP Superseal style connectors are mainly shit because lack of right crimping tool.

    Do's and Don'ts for e-bike battery care. What do you do to keep your battery performing at its best?

    Don't read any topics related to emtb battery usage as the whole bike will be end of it's lifecycle before the battery is useless.

    No power to motor - Purion dead?

    I disassembled the power connector from main tube to put it directly to spare battery. I changed 2 x 2016 battery to Purion and it didn't help. Tried this one also but forgot to mention it yesterday. The battery lights flashes also in case when I press the POWER button in Purion so there must...

    Rail - Dropper post

    My Trek Rail 5 2020 XL has the original TranzX JD-YSP18 (130mm travel, internal routing, 425mm length) and it's getting a little out of shape. I could try to fix it with Oneup V1 rebuild kit but at the same time why not upgrade to. Any idea/experience if the 31,6mm/240mm/610mm could fit...
