Yes, dogman, my motorcycles are long gone (riding in the Toronto area is suicidal) but you do learn about weight distribution. During my long distance bicycle riding days where we carried tent, tools, food, stove, clothes etc on our bikes we experimented with different weight distribution...

One thing i forgot to mention with front, frame-mounted battery is the superior shock absorbancy. Mounted directly over the front shocks, a heavy battery loves it. BTW It only cost me $60 to have the jig welded to the frame

putting the battery in the triangle does have its dissadvantages. 1) Less flow-through: a strong wind can off-set you, 2) not very stealthy-looking : try riding in "no motorized vehicle" zones, (appearences are everything), 3) damn crank arms The low weight distribution of triangle-placed...

Dingo, the battery is in line with the seat and and so all the weight is on one plane. Riding is superb. It could be a little awkward if walking the bike uphill for any appreciable distance.

nice looking bike lester. with motor on front wheel, battery probably is best on back. Can't you get it a little lower down? I remember my days of cross country biking in the 80's and a high load on the back made riding less stable.

Notice the battery is attatched to an aluminum plate by a dog collar and the battery itself is inside an insulated frozen food bag (insulation removed for better breathability). It is kind of rough looking because I had many issues with the ping bms' but when fully complete, (wires hidden) the...

Hi, There is an alternative to battery placement on an ebike. Most riders (I believe) use rear-wheel hub motors which neccessitate a counterbalance on the front. The solution for me is a frame-attached jig which holds the battery pack. My first build (3 years old now) was mechanically attached...

Did you see their 20 a/hr single pouch cell for $32? I was thinking of getting 20 of them and using a 60v ping board. I could probably do the work myself. But the shipping is another question. Does anybody know if the tabs can be soldered?

I saw these batteries too. I googled the owner, Carl, and he seems to have an honest reputation and respectable knowledge about e-car conversions. However when I asked him about details of a 60V 20 a/hr pack he wasn't too sure. For instance he said the pack would weigh 10.5 lb (way too low)...

I would not go with ping. Dbass says just swap this with that. Would you buy a car and change the motor so it is now reliable? I had so many problems with both ping batteries and bms'. With 2 batteries (cell problems) and at least 1/2 dozen bms' pain in the neck. Ping even instructed me to...
