The first gen bird scooters are too underpowered for me, even on a slight hill they have trouble (I'm 6'5" 270lbs).
The 2nd gen models with the additional battery pack are zippy enough that I'm comfortable riding in traffic, at least in downtown stop-n-go traffic, but I'm not a huge fan of the electronic brake that replaced the manual brake in the first-gen model.
I have seen a larger 3rd gen model but haven't ridden one yet, it's got a larger deck and the manual brake is back.
I'm avoiding lime for now, not a fan of their payment model. Bird just charges my card for each ride, lime wants me to pre-load some money into a lime account, no thanks.
