Anoying Spoke Problem - But otherwise excellent.

I love this bike. It has excellent componentry for the money and the finish is really good.
I do approx 120 miles per week on road over varying elevations sometimes riding quite hard and the bike has developed an anoying habit of snapping spokes. I think it's a week point on this bike due to torque loading in opossite direction from power assist acceleration and de-celeration through the disc brake. I have broken 4 spokes so far and the dealer says I'm not toqueing the spokes correctly and. I'm competent at wheel building but even let my local build specialist have a look and re torqued the spokes for me - still broke a spoke on a 30 mile ride the next day. I'm not a light weight at 16 stone but would have hoped the bike more than capable of coping. Considering having the hub drilled and and respoked with heavier guage spokes - Not ideal.
