The CrossCurrent uses a rear drop-out type torque sensor. The sensor sticks in about 1cm only on the drive side. The result is the frame needs to compensate for this and appears somewhat asymmetric. The wheels are true with respect to the center of the bike so it should track accurately.
Additionally the bike has a very tight RC (bottom bracket to rear axle distance), maybe one of the tightest in the e-bike industry. This makes the bike very nimble and has a bike-like ride characteristic. Tight RC can result in more bumpy ride, so on the other end it uses 700c x 45c tires. That is about as fat as 700c tires get to smooth out the ride.
Another thing is the bike uses a massive 52T chainring on a standard 68mm bottom bracket, so you can achieve high gearing to pedal normally at high speeds.
The result is great riding quality, but everything is fitting very closely together. If any part of the tire is touching the frame, check to see if the axle is seated all the way.
