    EGO Motor Kranked 2400 Watt Mid Drive Setup

    Hello all, I'm the guy who did the first high voltage 72V A2B Metro a hundred years ago. I haven't posted for a while but I'm here again to sell my Kranked/EGO mid drive setup. I bought the ~2012 Santa Cruz Nomad 2 with the conversion already done and rode it for a few years. When it finally...

    John, I use an iCharger 3010B which does balance charge up to 10S. There's a picture of it on the first post. I don't balance charge that often. When I do, they are pretty close. That might not always be the case though. I got lucky with these packs. Jim

    A2B Metro restoration / modification - Fechter's first Ebike

    I fixed my centerstand for good with a 1/2" Allen bolt, washers, lock nut and locktite. I drilled and tapped the A2B frame for the bolt thread 1/2"-20 if I remember right. I first tightened the allen bolt through the centerstand into the frame with locktite and then put a washer and nut on it...

    This spring I put two 10S RC Lipo stick packs inside my A2B Metro's down tube: https://www.youtube.com/watch?v=l09qAkCI08E I also put two sticks on top of the frame for 72V and a very centered mass. The bike goes 37mph (GPS verified) and handles great though I try not to park in front of any...

    A2B Metro restoration / modification - Fechter's first Ebike

    I have a hopped up 38 mph 72V A2B Metro and the fat Kenda tires that come stock are the reason for poor handling (after you replace the rear shock). As soon as I switched to Pirelli ML75 moped tires the handling improved immensely (tire size 2.5 x 16") . I would buy these moped tires and cut up...

    Resurrecting an Ultra Motor A2B Metro with 20S power

    I think I might start a project to build a sheet metal battery box that hangs under the down tube and secured with rivnuts. It would hold the two batteries that are now on top of the tube on my bike. I would move the controller to the space where the rear battery case slides in. That way I could...

    So I uploaded some more pictures for your viewing pleasure. These are the batteries I am using. I spent $520ish on the four and got lucky that they are well matched and stay in balance. That's my size 8 foot there for scale: Here are a few shots of the batteries mounted inside the rear case...

    It has been shown by Ypedal that 48V on the stock in-motor controller does indeed work.

    Resurrecting an Ultra Motor A2B Metro with 20S power

    Once the bateries are slid up into the down tube there is no room for anything significant. It would be good enough for smuggling baggies of stuff if you were into that. :P Of course, riding a 38 mph quasi scooter on city streets without registration might make you a target for the local...

    Altonk, I can offer to lend (and send) you my rear battery case. You could stuff 17 pounds of rocks in it to give you an idea on how the bike will handle with four batteries in it. You might find you don't like it bottoming out. I know you have a longer 6.5" shock back there but it would be a...

    Resurrecting an Ultra Motor A2B Metro with 20S power

    The bike is two-hander at any speed. It works fine at full speed but you need bigger/better brakes than stock. Taking weight off of the rear end enhanced all aspects of handling. The back end still gets a little choppy going fast around bumpy corners. There's just so much weight in the back...

    I don't have any specific performance numbers but it does go 37-38 mph. I can do a 14 mile round trip downtown running above 30mph on average. Is there any specific performance you want me to measure? I don't have a helmet cam. I do plan on shooting an overall video just showing the bike but...

    The stock batteries are child's play compared to rc lipos. I sold mine off a couple of month's ago. I also tried a 6.5" rear shock but didn't like the jacked up rear end. I'm a little short at 5'7" so I went back to a 6" shock. Good luck! Jim

    Ultramotor A2B Metro RC Lipo frame batteries Here I show how I successfully installed two Zippy 10S 5800mah long lipos inside my A2B Metro frame. I bought three foot long aluminum bar stock two inches wide and an eighth of an inch thick from Home Depot along with a $25 big industrial pack of...

    Resurrecting an Ultra Motor A2B Metro with 20S power

    Altonk, I am using those batteries, four of them and they work well. I did have them cleanly mounted in the rear battery case but they made the bike tail heavy so I moved two of them inside the down tube with a special aluminum and Velcro fixture that protects them. I mounted the other two on...

    2011 model year A2B Metro Gen. 2 strange vibration + noise.

    I use 200mm front rotors with 185mm rears with BB7 calipers on my A2B Metro. The brakes work well up to 38mph. I didn't much like the BB5 brakes.

    There is an A2B Metro in Brooklyn, NY on ebay for a decent price that has a "bad" motor. There is a decent chance it has a bad controller inside the motor and can be modified like my bike...

    If you are talking to me the OP then all you have to do is crimp and solder one 12AWG or 14AWG wire to each pair of winding wires and then get them out of the hub through the axle window. There's not much to it really. -Jim
