Yeah it's a small shame. I've hunted through the wiring, but no luck finding a harness plug to bridge for the European offroad button that I hoped for.
15mph looks terrible on paper for all that weight and cost, but wasn't as bad on the road after a test commute day Friday, finishing trip about the same time as most faster road bike commute rides.
I've only ever shattered that time riding the Norco fast for a battery test, after peak hour on a Friday evening, home by dusk, low pedestrian traffic on shared paths, got home in 35min with 32mph top cruise speed only reached a few times. That wasn't any real cycling though and I didn't enjoy it as much.
I did enjoy the cycle challenge of the stock A2B. I rode home with new wide panniers
carrying some new cycle stuff that had arrived with the panniers and had been sitting at work for a couple weeks, trickling it home in spare space on the road bike backpack. Since the A2B Metro has rear suspension, I used the backpack rack bungee cords under tension to the swingarm as pannier stays, it did a pretty good job to get me home safe, only one bit spot of rubbing wear.
I don't mind the soft start, I'm not wanting to wheelie it like the Norco
I was still able to cross the road quickly enough with or without pedalling to slip through gaps in traffic. Trying to figure out a removable auxillary battery option with either a 7Ah 36V watter bottle mounting type I have, or 10Ah 36V seat post type. Both options taking up luggage space with current ideas.
Has to be removable so I can ride on auxillary B batt, charge it at work, ride home on frame A batt and charge at home.
Factory option B batt would be ideal to keep more luggage options and convenience... but $650+ ouch. I emailed Ultramotor asking if any refurbished or unservicable B batt's, but no reply.
I was wondering what B batt with +12-18V (<60V) would do for top speed, if controller didn't drop current to keep the 15mph speed limit.
I saw mention of 62V on controller caps.
