@Ged I Ultramotor figured out in the first production runs of the A2B Metro bikes that there were problems with the motors; nearly all had to be replaced under warranty within months of purchase. An internal controller failure was most likelyto be the culprit; however, the issues did not end there. The internal battery was also vulnerable to memory issues (not an issue for current LiIon batteries, thank you!) and some failure of the cells, so riders had shrinking range. With that said, the overall design was and is striking in appearance, an incredibly comfortable ride and the company was proactive in handling the issues. Yes, it was easy to kick the keys in the downtube ignition. That design was changed at the next round of upgrades and the console display was added. Keys were never put on the downtube again...way too easy to damage the ignition.
What you refer to as 'digital vs. analog' is actually an internal controller in the motor vs. external controller. The internal controller version was replaced after a little over a year to produce a more stable design and over the following couple of years other wiring harness issues dealing with the cramped space at the bottom of the battery were addressed. That's about the point when Hero Eco bought UltraMotor. Now, Hero Eco is pretty quiet and is developing A2B as its own brand separate from their mass production bikes, etc. Must tell you though, the owners' of Hero Eco spent a lot of time in the US, very hands on that first year, visiting dealers and listening to lots of complaints!
Only the very last run of Metro's had the pedal assist option in addition to the twist throttle and some fancier digital display console. The Metro's with the throttle only at that time were from the previous year's production run and allowed the company to offer 2 different price points. The internal battery was always a 36V 11ah LiIon no matter which year model; however, with the introduction of the Alba and Shima, Metro's offspring and the newer, faster upgrades of the Rear LiIon battery Velocity and Hybrid, the internal battery went away.
I think our writer above, may have misread the manual or it was a typo, since a 12 hour charge is overcharging whether once a month or during regular use. My shop and the manufacturers recommend a charge of a couple of hours max (1 to 2 hours) at least once a month to keep the battery from degenerating or going to sleep. After a lengthy storage of a Metro, it helps to ride it hard and run that battery down (not dead), let it cool and charge it again. One or two repetitions of this will help prevent the pseudo memory issue that the early Metro's showed.
@Ged I, you have the later design, but what is going on with the bike? Here to help
Ok, so I collected the bike today and what a great machine it is. I couldn't ride it too far due to other reasons, but the bike looks and feels wonderful. My own thoughts to follow on the ride.
In the meantime I have a question if anyone can answer it. On the display it appears to default to KMPH and not MPH. When I chane the settings to read in mph it's fine, but as soon as you turn the bike off & on again it goes back to KMPH. Surely it should stay on mph as per the last setting. Or am I wrong? I know it's a small thing, but I'm not sure I want to fiddle with it before every ride. Anyone experienced this or is there some kind of fault?
A little update:
I didnt have a manual for the bike, but I did manage to print one. Thank you Joepah for the information. What was confusing was i followed the instructions on the manual for re-setting to mph, same as you state as above, however after turning the bike off with the key and turning on again, the settings were not saving. This was a head scratch moment as I couldnt figure it out. So I was lucky enough to find A2B on facebook and sent them a message, what a great response..within hours there was a reply that I never would have figured out on my own, or without emailing them.
For anyone else that comes across this issue the following may help. You do the procedure as above and confirm with the Mode button, but odly enough you have to do this three times, then it saves.
So the bike is set and runs perfect, went for a ride the other day to see how far it would run for, I'm a big lad at 17 stone (hence the style of the bike) I went for 17 miles before it went to auto cut out, then made it home off power (close to home) the bikes suspension is awsome, way better than other bikes I have ridden with normal size rims.
It did feel a bit odd as its a small sit up type frame, but after a while I got used to it. Not yet in a position to ride it daily but thats my aim. Great bike from A2B really please.
Not sure I understand the tyre size thing yet it does say on the tyre wall that the tyre is updated with a thicker wall or something to that effect. I have deflated both tyres and used the slime stuff to help prevent punctures, hopefully this will help. Was just wondering if The AA would recover me and my bike as I am a paid up member. Would an electric bike be covered (no index plate obviously) anyone tried this with any recovery service?
I thought the distance of 17 miles was realistic, even being light with the throttle and pedalling. It's about what I expected.
I have had an electric bike before, a Smarta LX this is The Electric Transport shops kind of in house brand. I still have it and it's gonna be passed to her indoors. To be fair it's been a great little bike, but no where near as good or smart as The A2B (in my opinion) I love it and am looking forward to some good rides.
