My best advice....ride the Turbo. Compare it with the Trek. The Turbo is a very smooth, impressive bike to ride with its pure torque sesing system. Further the Turbo has many levels of assist from 10% to 70% in 10% increments as well as full TURBO mode. However, the TURBO is probably harder to service. The rear wheel is difficult to remove and the componentry (except the cluster) is proprietary due to the heavy GOSwissDrive hub. The Trek uses standard (though heavy duty) rims, spokes, hubs, etc. The Bosch mid-drive system is well debugged, understood, and used by a number of manufacturers, though I think the XM700+ comes with a 400 Wh battery, while the Specialized comes with a 468 Wh battery.
Ride them both. Decide which one feels best to you.
Ok, thank you!
