Me and my friend have had a series of bikes since September last year, which include, the 2019 LT7, LT9, LT9.9, 2019 Levo Carbon expert, 2019 Levo FSR, keveno Expert and 2019 Powerplay Carbon 70.
The bosch motor is more powerful than the Brose in the Kenevo ( the 1.3 motor) but not quite as good low down as the Levo motor ( 2.1 brose). However in a drag race the Bosch and 2.1 Brose are the same, its more down to the riders legs. We currently have the LT7, the 2 Levos and the RM left between us. The Trek is similar to the Kenevo at descending, though not as good. The Trek is really good at climbs.
The Kenevo is a bargain as they can be had in the 4k bracket.
The RM eats them all for sheer power though and is very lively/fun to ride.
Ive put 1300 miles on the LT7 and its been great.
If you want a trek get the LT9 as its very similar in spec to the 9.9 and is worth the extra money over the 7. But really it comes down to how you want to ride and where you ride, plus what bike fits you best. Weve found the Kenevo to eat the most battery compared to the other bikes. The Levo 500watt is pretty much the same as the bosch 500watt from what weve seen on identical rides.
