Equipment
9C 3005 Motor
72V@40A Grin controller
72 V 10 A Bosch battery
Thudbuster
Softride stem suspension
Cycle Analyst 2.4
Sapin spoke laced DM24 rear wheel

I built the battery boxes and rear rack with 1 1/2 aluminium angle stock , 1 in square stock, and 3/16 aluminium flat stock
I placed the bosch battery packs inside in vinyl gutter square tubing then covered with 1/16 in aluminium diamond plate and bolted them to the frame

So far it has been very easy to ride. My last build had the batteries on the rear rack so it was not balanced well. Since I moved the batteries to the downtube and cross bar it handles like a dream and NO annoying rattles. It tops out at 60 KPH (40 MPN) and draws 40 A@ 72 V so about 2750 watts.

Yes I have had the Softride suspension stem for several years. I really like it. It has about 3 in of travel and does a good job absorbing the road bumps, I was going to put a front fork suspension on my bike, but I do not like the added weight. Thanks Neil
