    Yamaha XPC-26 Battery

    You can get all the stuff from Nkon.The cells you mentioned are overkill. You can save a lot of money by using 2500mah cells or whatever they have on offer. Use slotted nickel strip, then you can get good welds with one of those cheap Amaxon welders. Your bike will draw around 15 amps max, so a...

    Brexit, for once some facts.

    The story has come out today that the laptop contains thousands of images of Hunter Biden raping and beating underage girls (like 10 yrs old) in China. Some are screaming for him to stop. Does that compare with a guy and his tax return? if you think so, you're very sick. The story has come...

    Help! C300 Handlebar Display

    It would be a good idea to get a speed sensor in case the one in your motor packs up, and I would get an 8 pole PAS as well, just in case. They don't cost much when you buy them with the controller. When the controller comes, ask again, and we'll show you how to connect it. Don't start until...

    Broken my 'new to me' Wisper bike after 5 minutes

    That could be a clue to what's wrong. disconnect everything except the battery and measure again. if you get 5v again, plug things in one at a time until you find the culprit that's pulling it down.

    HELP please- Error code 10 Voilamart 48v 1000w Rear wheel kit

    Unfortunately that controller doesn't have one of the normal layouts. The 5v regulator could be anywhere and is probably hidden by all those wires. I might be able to find it if you can take a load of clear photos with the wires pulled in different directions so that I can see all the...

    Cyclematic powerplus power problem

    There's nothing yet to indicate that anything is wrong with the controller. If the throttle doesn't light up, it shows that you have a problem somewhere else. Until you fix it, a new controller will be a waste of money and time. The problem is between your battery and the controller. Check the...

    Broken my 'new to me' Wisper bike after 5 minutes

    The pedal sensor signal wire voltage switches between 5v and 0v as the pedals rotate. you can't measure it static. You already confirmed that you have 5v on the 5v rail, so you don't have to worry about the pedal sensor. Your fault code is something different. You're going round in circles with...

    Brexit, for once some facts.

    Tim Pool is and has always been traditional left wing, not right wing. He said he voted democrat in the last election, but will probably reluctantly vote for Trump in this one because he's not happy about the way the dems are going. He's not a Trump supporter per se. These two parties can't...

    Help! Looking for an Ebike carrier for a 2019 Ford Focus

    I've tried a couple of those hatchback type racks to carry an ebike - totally useless! It's much easier to take your wheel off, turn the handlebars on the stem and put the bike inside the car. You can take both wheels off the Rockrider, so it should easily fit in the back with the seats down.

    Cyclematic powerplus power problem

    Did the lights on the throttle light up. If not, no battery power was connected. Don't start jumping to conclusions, it will only slow you down. The two wires soldered together are the 5v to power the pedal sensor. The 5v comes from the red wire from the controller that is connected to the...

    Brexit, for once some facts.

    As I said in my last post, the guy that sent one of the emails has confirmed that he sent it. It's all detailed in that Tim Pool vid above. Guys like Tim Pool and Styxhexenhammer666 have been doing this sort of reporting for many years. They don't make mistakes, otherwise they'd have been shut...

    Wiring QS-S4 Display Throttle

    There should be 6 wires: 3 for the throttle, one for the lights, one from the speed sensor and one from the battery to power it and work the battery meter. It's very important that you identify the battery wires on each side of the connector and make sure that they connect only to each other...

    Help! C300 Handlebar Display

    Bike riding is not a good qualification to do electrical installations. everything is easy when you know how to do it. To install a controller, you need to understand, you need very basic knowledge of wiring and you have to be able to solder. These things are easy to learn, but if you're...

    Broken my 'new to me' Wisper bike after 5 minutes

    The motor is connected directly to the battery, but blocked by the mosfets. No other components are involved. You checked the mosfets, so your theory doesn't hold any water.

    Brexit, for once some facts.

    It's not just "some right winger on a Youtube video", it's Rudi Giuliani, the guy that has a long history of success in clearing up corruption. Here's Tim Pool on it - well worth watching. Tim is a traditional left winger, like me. Emails are confirmed as genuine and one of the guys that sent...

    I thought someone might say that. Biden rally. At his last one, the 20 trump supporters jeering outnumbered his own ones: This is the overflow of people that couldn't get into Trump's last rally:

    Broken my 'new to me' Wisper bike after 5 minutes

    I told you the LCD works independently. It has its own CPU. Check the LCD's cable and all connectors between it and the controller. We started on the basis that your bungee had damaged something, but we've checked and eliminated everything at that end of the bike, so whatever happened was...

    HELP please- Error code 10 Voilamart 48v 1000w Rear wheel kit

    If you can tell us which wires you shorted, I can tell you what's likely to be damaged. While you have no 5v, the controller's cpu can't work, so it can't communicate with the LCD, hence your error code. If you can solder, the 5v regulator costs a few pence and is normally very easy to replace...

    Help! C300 Handlebar Display

    You can get your bike working on throttle and PAS1 by cutting off the cable from the LCD, then strip back a bit to find the red and blue wires. Either put a switch between them or twist them together. That should keep you going until you find a replacement LCD. Brainpower with LCD is about £40...
