One nice motorbike project here is Bennelson Vectrix to Leaf cell conversion:

18 Leaf cells fit the Vectrix frame perfectly!

Still, that Vectrix has just 9 kWh.

I'm building a portable plugin kit for my car, based on LiFePO4 cells. It has just 1.4 kWh and weighs over 15 kg including boxes, cables and BMS. (still highly portable, as the pack is split in 3!)
A pack with 10 times its capacity would be too heavy for a motorcycle.

Electric bikes are perfect for a relatively short commute. Charged every day, not using the entire range, you can keep doing that for years and gain back the investment.
Making a long range EV is hard and costly, and unless you do use that range on a near daily base you probably won't make up for the cost.

I won't say it cannot be done. The Stella solar racing car has a 15 kWh battery pack that weighs just 63 kg. Light enough for a fun midrange electric motor bike. But probably not a cheap one...
