1.) Stromer’s new Cyro drive is used in place of the ST2 line’s Syno drive. Both rely on 500-watt motors. The former doesn’t have
the same peak power, but does have many of the other same features like several levels of regeneration. 2.) Shimano SLX derailleur
mated perfectly with the gear range chosen. We never ran out of high or low gears as needed. 3.) The Omni display is a ;rst for an
ST1-line bike. It offers full controls and connectivity via the Stromer app. 4.) Stromer’s Roxim EX light is a big step down from the
massive Supernova light, but this one is still plenty bright.
The bike accelerates very well in the
factory setup mode. We rode that for
a while, as the performance was good
and range was incredible. We weren’t
being conservative, and the battery used
about 1 percent per mile at 90 percent in
level 3 (the highest assist level). We then
tweaked the torque sensor’s sensitivity to
a higher level and, oh, what a difference
that made! It went from good to great!
Yes, range was affected, but we’d trade
that range for more fun factor. If you were
riding this bike to work, you’d de;nitely
get there without a sweat. You could
absolutely turn off the electrics on the
way home, or even turn on regen mode
for an even greater workout.
Gearing is perfect for this bike. The
big 52t front sprocket combined with
11 gears in the rear (11-42t) Shimano
SLX set means it can climb hills or
race across ;ats and you never run out
of gears. It does love to cruise in the
25–28-mph range and gets there quickly.
Another plus for commuters, you can
go nearly the same speed as traf;c for
safety and visibility. In some large cities,
you’ll be able to go faster than traf;c.
The Omni touchscreen display
makes it easy to see remaining battery
power, current power level, addition-
al controls and settings. Some riders
complain that having the display down
on the top tube instead of on the bars
takes your eyes away from the road
too long. If done safely, it’s at-a-glance
easy and shouldn’t pose a major issue.
Further adjustment can be performed
via the app, as can tracking the bike via
GPS and remote-locking the rear hub.
Imagine someone stealing your bike
and you being able to lock out the rear
hub remotely so they have to carry a
Conversely, there’s a walk-assist func-
tion that will help you push the bike up
hills or across places you can’t ride, pow-
ering the bike along at walking speeds.
Because the battery is housed inside
the downtube, bottle-cage bosses are in
place and ready to handle bottle cages or
any other accessory you’d like to bolt on.
