    A2B Octive/Metro purchase?

    Hi Audisport09, Well after 3 years of sitting (both self & bike!), I charged up the A2B Li-Po packs today and found that they had 'stored' flawlessly and have remained stable & balanced cell-wise. :) Attaching a quick screenshot from the 'ChargeMaster' software that came with the charger. I...

    A2B Metro (Gen 1) Restoration and Upgrade

    Yes, the A2B Excel was labelled/sold as an 'Electric Scooter' and appears to have been fitted with an 800W version of the UltraMotor. I guess the controller was in the frame:

    A2B Metro (Gen 1) Restoration and Upgrade

    Really beautiful work here.. thank you for sharing! :) ~ Maybe two securing bolts through the torque arm/plate? ;) :bigthumb:

    A2B Metro (Gen 1) Restoration and Upgrade

    Yes, although you will get a slightly higher rear ride-height with the 150mm unit, you should also be able to adjust it's air pressures to best suit your setup/body weight etc. Sure, who knows whether A2B custom made their seals, or used an available 'off the shelf' unit. I guess you could get...

    A2B Metro (Gen 1) Restoration and Upgrade

    You mean rear, presumably? I got one of these (125mm, I think) to replace that horrid standard A2B sprung unit: https://www.ebay.com/itm/KS-A5-bicycle-soft-rear-shock-absorber-device-mtb-bike-rear-suspension-shock-New/283533376695?hash=item4203e7fcb7:g:tKcAAOSwPdhdGbBk But will probably...

    A2B Metro restoration / modification - Fechter's first Ebike

    Cool.. sounds like you're getting it all under control now anyhow! - If I recall correctly, I also took the opportunity to thoroughly clean/flush out the tubes etc & replace a couple of rubber O-rings for good measure, before adding fresh lube prior to final reassembly. Enjoy your new...

    A2B Metro restoration / modification - Fechter's first Ebike

    I think this is the very reason 'fechter' describes: 'quality time with my bench grinder thinning out the (socket) wall enough to fit into the recess on the top of the fork'? I also made this mod by first grinding down the wall thickness of/around the metal socket head and it then fitted/worked...

    Charging issue on Ultra Motor A2B Metro

    That little Korean spot welder is super cute! But I have also soldered these batteries with no apparent ill-effect. I think the (obvious) trick is to allow only a minimum amount of heat to conduct into the cell, in order to prevent/minimise any damage etc. Thus (contact) 'time' is of the...

    Charging issue on Ultra Motor A2B Metro

    ~~~ Glad to hear that you successfully found replacement Battery & Charger! :) Do you mean that you would like to test/restore life to the original (A) 'Battery' - or instead to the individual 'cells' of that battery? - It would likely only take one or two apparently 'dead' cells cause the BMS...

    A2B triangle battery box

    :) OK! ~ So a small red notice attached: "In case of Fire - please kick the shit out of this box until it completely parts company with the bike and/or is extinguished!" ;)

    A2B triangle battery box

    Sounds good Audisport09! Tough & non-conductive. I take it you have since given up on the option of refitting batts to the front fame tube - and don't mind losing the 'step-thru' format? Possibly too large for a home 3D-printing setup, but might be worth talking to an automotive plastic welder...

    A2B metro charger

    If your battery pack really is new and has also never been used, then the chances are that it has never been charged either? - Just a thought, but perhaps, providing there are no completely 'dead' cells, it may first be worth trying to coax some volts back into those cells before...

    A2B Octive/Metro purchase?

    That sounds about right to me for a used & standard rear pack.. but mine was 'dead on arrival', so I never got a chance to experience/test it before rebuilding. (Lots of info elswhere here tho. ;) Some people have fitted a larger crank-chainwheel too, thereby raising the gearing to the point...

    A2B Octive/Metro purchase?

    No worries 'robbiesd'. Jump on eBay.. or even visit your local bike shop? Personally, I am still using one of these: https://www.ebay.com/itm/Kind-Shock-Kindshock-KS-A5-RR1-Dual-Air-Rear-Shock-150x30mm/263401048971?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 But have found...

    A2B Octive/Metro purchase?

    Congratulations first of all! Sounds as if you now have yourself an excellent basis for some suitable tweaking & 'personalisation' to your own setup preferences anyway! :) Presumably you still have the standard rear 'shock absorber' fitted? Though in fact, in my opinion, it is more of a (too...

    Aint that the truth! And thanks.. that 2000 Aprilia was clearly WAY ahead! ;)

    A2B Octive/Metro purchase?

    OK! Sorry to 'misinform'! Maybe you'd like to correct the A2B Wiki on this?: https://en.wikipedia.org/wiki/A2B_(brand) - which states: "The A2B company launched the metro in 2009, the first specially designed bike frame for electric motors." As far as I am aware, the Metro line was built first...

    A2B Octive/Metro purchase?

    @ 'robbiesd': So glad you had at least already seen that Ad. :) His bikes clearly are in exceptionally good all-round condition. ~ I can't help wondering how long it will be, before machines such as his actually start going back UP in value again? 20 years? Reckon, as it's 'buyer collects'...

    A2B Octive/Metro purchase?

    @ 'robbiesd': Obviously, everyone has their own view & price limit etc, but did you check out that TX ad at all first? A wealthy guy clearly bought x2 @ $3,200ea new - and they have been sitting in dry storage in his garage & essentially unused ever since! To the right person, $1600 (+ rear...

    A2B Octive/Metro purchase?

    Even less 'unreasonable' might be (one) these?: https://www.ebay.com/itm/A2B-Metro-Elec ... SwKz5d88ud x2 brand new Gen 2 A2B's at half original price paid.. AND apparently willing to sell *rear battery pack(s?) separately*. This is rare. ;) Texas.

    A2B Octive/Metro purchase?

    No worries Audisport09 - a pleasure to share! Yes.. you clearly have the general 'picture' now. :) Regarding paralleling balance leads, my thoughts at the time were twofold: 1). Available space was getting very tight in there.. literally down to millimeters! 2). Factory Li-po battery-batch...

    A2B Octive/Metro purchase?

    Each to their own Eh! Personally, I really like them for their super-comfortable riding position. Altering front forks/rear shocker & fitting moped tyres etc can transform the handling & frame-reliability characteristics too. As one of, if not THE first fully 'bottom-up' designed electric bikes...
