sion action. On one ride we did 14 miles
with 2100 feet of climbing, and we ran
the bike at the highest level of assist at
all times, though we did opt for level two
on descents to aid bike control.
Despite the extreme use, the battery
was still well above half power left. On
another ride the Thron went 32 miles
and over 5000 feet of climbing. As a
habit the rider conserved a little battery with level two on the way out, but
as soon as it was obvious that range
wouldn’t be a problem, he kicked it up
to full power and left it. There was still
50 percent charge left!
Much of our time was spent with
Bosch-powered e-bikes that have 11
amp-hour batteries, and the feeling of
freedom we experienced in not worrying
about range was exhilarating. Not to
mention the fun of running full assist at
almost all times
With the Thron you get an e-assist
mountain bike that is not just legal but
responsible. The assist motor is all but
silent, and there is power for days while
climbing. There is no throttle option, so
you must pedal it to get the job done.
This is a fun bike built with quality
craftsmanship, and it shows in the ride.
If you crave the feel of a bicycle but
want plenty of help with the climbing,
the Focus Thron is the bike. ■
All of the controls are compact and out of the way.
They are easy to use but not
prone to damage.
Focus and RockShox did a
fine job on the suspension.

shaft make suspension setup
