Ok first of all I own bikes, a lot of bikes and I even own a variation of the fabled STEALTH BOMBER which is hella fun but let me just say the EUNORAU DEFENDER S is a down right monster. Sure it’s not cheap but neither are Lamborghinis but you get what you pay for.. For those of you worrying about low end torque, STOP WORRYING bc this bike has more than you’ll probably ever need. The pedal assist works great, minimal delay on and off with a rather accurate sensor setup. The brakes are better than I’ve heard people describing them(maybe Eunorau has addressed that) id say 8.5 out of 10. I just can’t say enough about the power bc going in I thought 750 per wheel should be ok, now I’m thinking it’s a little absurd but delightful as it pulls and pulls and pulls. Did I mention get the extra 17ah battery bc these 750hubs are thirsty and you don’t wanna deprive them of voltage. One thing though the 80mi stated range is well laughable unless you never leave assist level 1 and run 80lbs in your tires to lower friction. But who cares I can live with a realistic 50-60miles real world.. GET THIS BIKE it’s down right delightful. If you don’t get this you’ll regret it when the guy down the street gets his and does donuts around your 350w single motor budget bike..don’t be that guy..
