Help! Weight limit/strain on converted e-bike

Hi everyone,

I'm still pretty new to e-bikes, so I'm aware this may be a daft question - but here goes.

I have a hybrid converted with a midrive Bafang BBS02. The battery and motor together add a good 10kg to the frame.

I'm wondering if anyone has found adding loaded pannier racks to their E- bikes with a similar set-up, to be a problem at all?

I don't know how much weight a bike frame is designed to take, especially when the weight isn't spread out very evenly. Is warping/flexing of bike frames common in these situations, or is this a non issue I don't need to worry about?

I'd like to add a rear pannier, on which I'd be carrying between 5 and 10kg - a pretty light load in the scheme of things I know. But I'm wondering if the 5kg battery on the downtube and 5kg motor under the BB shell - plus up to 10kg on a rear rack, could together cause strain and lead to damage/instability over time.

It's an alluminium frame

Thanks in advance,

H
