Trek have opted for a Fazua motor system, which provides power
at the cranks (rather than at the rear hub). There are pros and
cons to either option, but one key advantage of a crank-based
system is that you can easily swap between different wheelsets,
using any standard road wheels.
The 250 Wh battery can provide assistance up to the legal limit
of 20 mph (although there's nothing to stop you pedalling faster
than that yourself!) and Trek quoted a range of up to 65 miles with
continuous assistance (but in reality you're unlikely to have the
assistance turned on all the time).
At launch Trek are offering the Domane+ LT as a complete bike,
with an Ultegra mechanical groupset and the tough, well-engineered
DT Swiss G1800 wheelset at an SRP of £4900. This build weighs in at
13.56 kg (29.9 lb) in a 56cm size, which is pretty impressive for
an e-bike, and should make for a lively ride.
Project One configurable build options will be available early
in the new year, allowing you to mix and match components to create
your own unique build.
