Our newest addition:

Comes with 52V 17.5Ah battery in the frame and a choice of 14Ah, 17.5Ah or 21ah as a range extender. The battery comes equipped with a battery dualizer that switches automatically between batteries as one of the batteries get low.

Looks good. There's a typo on the XXL wh that you might want to fix.

Dual Battery:
XXL Combo

52V 17.5Ah 910Wh +
52V 21.55Ah 910Wh
 
I'm not familiar with Bafang dual battery setups. Is the dualizer designed to keep the voltage within a preset range between the batteries?
 
According to the website they don't have frames in stock (DUO 3 >17" frame) that can carry the largest battery capacity at this time.

BBSHD before they apparently discontinued them. Can't find it on the website anywhere. Only real disappointments have been the brakes and headlight. Overall very happy with it. 1000 miles in 7 months. Any issues I had to get resolved with Biktrix support went over without a hitch. Customer support has been very good for me.

This heavy and fast bike needs 180mm discs with quad pistons at minimum. 160mm w/ dual pistons just isn't strong enough in my opinion. The headlight is just adequate. If your do a lot of riding at night in poorly lit environments you will need something brighter. I am considering getting the Armageddon upgrade or something else I can run off the main battery.

man 500.00 for the magura mt5 upgrade I could buy them for 280.00 anywhere. ouch.
I will be upgrading the brakes this winter while the bike is down for the season. I'd love a 203mm rotor but I don't think the RST guide can fit it. 180 and mt5 is probably what I'll end up with.
