I had this dilemma back in July. I chose the S2 for its massive battery and offroad capabilities. Both have its ups n downs.
Baja is almost twice as much when it’s all said and done if you put bigger battery. Bigger motors and esc upgraded.
Evolve carves like a champ and weighs less.
Baja takes offroad to a whole new level.
Baja has capably more range.
Your decision may be based on…
Where do you want to ride? Do you need to carry your board or store it during your commute. Ie work , school etc.
Evolve has extra batteries for purchase. Though swapping in my opinion will eventually strip the hole where screws go in. (I had a carbon gt).
Baja S2 is a different beast.
