Horwin CR6 range is a lie

Let's get to the bad news right away. Total range I got in sport mode was 63 KM. I rode around town, through some rural areas and a few hills. I weigh 195 lbs and am 5'11". Vancouver company I bought from says I should get 100 KM range in sport mode. Horwin website says 120 km and doesn't specify what mode I need to be in to achieve that. Neither sites discuss how heavy the rider should be to achieve optimal distance.
Good news this bike does really well on the hills. Much better than the Super Soco. However a couple things to note. Obviously range is garbage compared to what is advertised. I would be fine with 90+ km range but 63 km when you advertise a minimum of 100 km is false advertising. ALSO when you hit 19% the bike drops a ton of power. You will see 6:27 mark that I am doing just over 70 KM/h and without laying off the throttle it goes down to 60 km/h all by itself. I can get back to 65 or 66 at times with a long straight away but it takes a long build up. Feels very unsafe riding through town with little to no power. Really make sure you have time to pull out in front of traffic.
Not worth the money. I definitely feel lied to. Really wish the million videos I watched before buying this bike were more honest. Clearly they were paid by Horwin and not honest reviews.
