    High tire pressure or low pressure?

    Reading this post, i can appreciate high vs low tire pressures, however one thing which baffles me is how some tires can be inflated to the likes of 60psi + or even 80 to 100psi?. Maybe its an international conversion thing which i am not understanding... I have - schwalbe MTB tube 26" -...

    I love my MAC - screams 55km through traffic however for such an expensive toy; i have to be cautious of not leaving it hanging around the city for too long. I'm also now looking at other forms of electric such as boosted dual skateboard or this below.. ;) I came across this a few days back and...

    key lock switch question

    Running 14s.. the question though still stands as i am electronically inept. So the key lock can link in series on the 'ignition' wire and optionally the ignition button itself (from Cell_Man's kit)? Also where do you put the circuit breaker? Isn't the point of having a basic & cheap key lock...

    key lock switch question

    hi guys! i am looking to also put a key switch to the controller for that little added security of knowing some clown can't just turn on the bike by accident and turn the throttle... @Tench - from your advice - just to repeat and you can get any basic key switch (like out of an old computer...

    MAC8T: Limiting via the controller or Cycle Analyst? both?

    Thanks all.. dogman. Makes perfect (logical) sense. BMS --> Controller --> CA. I got the 3 speed switch and upgrade phase cables... though the CA would make the 3speed almost redundant... Not too sure of what these battery shutoffs you are referring to - care to elaborate? So it looks like in...

    Supertux1's First eBike: Yet Another Commuter

    So i bought pretty much the same as you did in terms of the mounting the controller upside down - love it... what i didn't think of properly was that project box; i bought one that is too big and had to cut it down to size and now the back is exposed with all the wires. i didn't consider...

    XPD: open-source keywin e-bike lab replacement

    Nuts! its too late now. I've already resetted to one of the profiles on XPD! ;p i'll get on to Paul. The eLBS said the battery from Paul are good for a first ebike, He's just advised to lower the amps on the controller to try prolong the life of the battery. MAC 8T Rear, Controller Type: 12...

    Supertux1's First eBike: Yet Another Commuter

    I have to say this is awesome; i have bought as much of the same parts as yourself. I should of given more thought re: the rack as the 26" doesn't give much clearance. Now i've had to order the 29". ;( Are you able to take snapshots of the back of your bike and how you stuck the controller...

    Mac, Triangle A123, Giant Hardtail Commuter - 1st build

    Hey ed, looking through your threads however wasn't sure of the answer. - Did you end up getting the 9xmosfet controller or the 12xmosfet controller (then limited to 30A by the CA)? If you are on a 52V battery - aren't you effectively running 1.5kW @30A?

    HS4065 - A newbie kit for commuting

    thank you all for your advice. The reason why i chose direct drive was for reliability and maintenance. Less parts; less worries? Thats a generalism naturally.
