Hey guys .
Looking for some guidance as to which wheel size I should go for on my first conversion. I will ride mainly on roads/bike lanes but these are quite rough in my area as often the bike lane to the side of the road is quite unpleasant to ride with the constant dips and road unevenness.

The proper bike lanes aren't much better so I'm wondering whether I should get a 29" wheel (and bike) or a 27.5

I currently ride a crossfire e which is smooth but I feel all the bumps (maybe more as the forks are seized).

The motor I plan to strap to the bike is either a 48v 500w brushless ot 36v 500w/750w geared.

Thanks in advance

I like your thinking, and do consider thicker tyres if the bumping in any way annoys you. Front and rear suspension are a must in my book with my back.
Best wishes and let us all know how you get on.

Most are capable of being able to fit 27.5", but not the other way around, or you could go for a mullet option with 29F/27.5R

As above, full suspension will give you a considerably more comfortable ride.
Have you a budget figure in mind ?.

thank you. I want a minimum of 2” thick tyre so that should be ok. I think 27.5 has wider tyre choices so that could be a factor in my decision
