I would be a bit worried that the extra weight compromises the structural integrity of the frame. 2kWh are heavy

high quality heavy 18650s weigh about 2 oz. 190 of them would weigh about 24 lbs. Throw in another 6-10 lbs for bms, wiring, casing and errata and it's not that bad.

I would be more worried charging that huge home built battery pack. I'm sure OP knows what he's doing, but I wouldn't want to bet my house on it.

There's significantly more variation in weight between riders. If you're under the frame's weight limit, including battery, you're fine.

Bikes typically have a weight rating. Mine has 150lbs of cargo capacity (is a cargo bike).

    I don't know if this figures into the engineering formulas, but an e-bike needs to be stronger due to the higher speeds and power levels. On a human powered bike, if you're hauling 150 pounds, you're probably going pretty slow.

    My friends who have e-bikes go through a lot more "consumable" parts such as chains, tires, brakes, cogs, and bearings.
