A bit overenthusiastic i know but #FatBike #Bafang #+1000w almost puts you on the darkside on EBR #DIY would tip it, #Carbon might trigger them though
so company is always welcome.
Underpinning my suggestions is one thing really, i think you're looking for quite a serious tool for quite serious uses and lo and behold cycling across frozen lakes..... 2300w is about having it and not needing it rather than not having it and needing it; deep snow, hills and fat tyres = power plus you want a little headroom on that power, you can always ride it in low power and know you have that ace in your pocket should you need it i also picked up that you want a bike not a motorbike as you already have one so you're unlikely to rev n rip, Kindernay is rated upto 160Nm yes you could do that from a stop by just using throttle but if that isnt its purpose then i wouldn't worry too much as the torque sensor will do a fine job.
Sorry to do this but...... you might need a second battery, battery+cold=-Ah also higher wattage will be consumed in the colder months in snow, you don't want a flat battery in deep snow miles from home, these things let us go places we probably shouldn't so do it safely.
You're gna have a blast i can see it, 2 dogs belting around in the snow, YEAHHHH. #jelly
