Every e-bike owner solves the same problem badly. You arrive somewhere, and there is nowhere to put the lock, the charger, the waterproof or the helmet. So you carry a bag, on a machine designed to carry things.
The MZFT is the first Super73 with internal lockable storage built into the frame — somewhere to stow the battery and everything else after a ride.
Read the range figure before anything else
15 to 20 miles on a single battery. That is short. Super73 quotes 20+ miles at 20 mph under throttle-only operation, which is the flattering version of the same number.

Fit the modular second battery and it becomes 35–40 miles, which is a usable commuting range. The second pack is sold separately, so the honest price of an MZFT that goes a sensible distance is above the $1,995 headline.
520 Wh (52 V, 10 Ah) primary battery; a second pack is optional.
20 mph top speed under Class 2 operation.
Internal lockable storage and on-board USB charging.
85 lb weight; 250 lb rider limit; 27-inch seat height.
Recommended for riders from 4'10" to 5'10".
The storage compartment is the feature. The single-battery range is the reason you should budget for the second pack on the same day.
Sized differently to the rest of the range
The MZFT's 27-inch seat and 4'10"–5'10" height recommendation make it the most approachable bike Super73 sells for shorter riders — and a poor fit for tall ones, who should look at the S2.
The 250 lb rider limit is also 75 lb lower than the S2's. That is a meaningful gap, and it is the one specification most likely to rule the MZFT out for a buyer who liked everything else about it.
Who it is for
Shorter riders doing short trips who want somewhere secure to put their things. Within that description the MZFT is the most thoughtfully built bike in the range and the cheapest.
Anyone commuting more than about eight miles each way should treat the second battery as compulsory rather than optional, and price the bike accordingly.
