Good hardtail bike to convert rear hub ebike?

[mt247]

Which one you think would be the best option for ebike conversion with rear hub motor(500W MXUS XF15)? After riding for a while with my hybrid with no suspension I'm going to switch it to something with 100mm front suspension. I'm mainly driving on roads (which can be in a bad shape during winter when it's snowing), bumpy gravel roads and some forest trails. I'm mainly using tyres with really high puncture protection so they are a pretty hard ride with no suspension and going +18mph/30km/h

Currently I'm thinking about to get one of these used: Cube AIM/Analog models, trek marlin 5, White xc 290, Ghost kato. Any experiences with those or do you have anything else to recommend?

I think this site is the best one to help me, very knowledgeable people here. None of those articles talked about converting them to ebike to be honest.

I have fitted rear hub motors to 2 "modern" alloy frames mountainbikes, advise you check how deep the rear dropouts are. Both of mine had quite shallow dropouts - making it difficult to stop the axle rotating under full power.
Adding a torque arm is a good choice but finding a bike with deeper dropouts would be better (maybe an older steel frame?). Expect plenty of good advice from folk here with more experience.

Thanks for the information, didn't know about shallow dropouts before. I have 2x torque arms with my current bike and going to use on the new one also. Steel frame could be nice but there aren't many with disc brakes.
