I went for a first short ride today and am impressed. Plenty of power, boost mode let's you fly uphill and the most surprising part: range!
I just went to my local trail. On the KSL I've reached the top at around 30% battery left, all in Turbo. On the Shuttle SL I still had 60%, after ~5.2km, 550m up, just shy under 30mins, all in Rocket (10-15% steep avg) and 2x boost on technical climbs on wet ground with rocks and ~20-25% steep ramps.
After 15km (30% climbs, 30% DH, 30% flat) and ~1h I had over 40% left. On my first ride! So the battery is not at full capacity yet and it was not really warm either (~10°C). Tires are DHR DD MaxxTerra and Assegai Exo+ MaxxGrip. So nothing rolling as well as the stock tires..
The motor is pretty silent, pedaling in breeze is very natural. The bike is light, agile, very nicely balanced. Just love it! Glad I've chosen the Shuttle.
