Overall good, a few downsides.
Purchased 2 weeks ago, have done 200kms so far commuting to work and back. It's a 26km round trip with a few of small hills and I think I could just get 3 days out of the battery if I went easy on the throttle. Handles the rain fine, I've been riding it for 40 minutes at a time through heavy rain and puddles and haven't had any electrical or mechanical issues. The motor will cut out for a few seconds if you jump off a curb too aggressively but it's come back on within 5 seconds the two times it's happened to me. The seat was very uncomfortable if you spent too much time sitting down, I solved this problem by just standing up while waiting at traffic lights and that totally eliminated the pain. It could definitely do with some rear suspension, so if you're cashed up I'd recommend spending the extra $1600~ on the RX-E. All the components work well, the forks were a bit annoying to get air into but it worked out fine. I've managed to hit 51kph (on private property of course) with a full battery.
The rear cassette means if the battery dies you can actually peddle the bike without assist, you just won't go very fast.
I would definitely recommend the bike, but if I were to spend the money again I'd spend the extra and get an RX-E.
Rated 5 out of 5
