best hub (excluding hummies) would be loaded hubs, next best is possibly neohubs.
after those two, might be hobbywing hubs (and u can use cloudwheels donuts if u care about that), which can be found from most chinese prebuilt hub board, except meepo, because they don’t use hobbywing hubs.
meepo 100mm hubs also isn’t too bad if u mostly ride on smooth roads
for dd drive, there are only 2 options in the market rn iirc. either TBDD or elofty v3, both have hanger bending issue, but TBDD can be upgraded using @Tony_Stark’s new hanger design, if u r on the heavy side, maybe go with that option. elofty is a hit or miss, but they are on the cheaper side if u r on a budget
e: ooops, i just saw u r looking for prebuilt, well…either chinese prebuilt board or loaded unlimited kit might be ur best bet.
Hobbywing hubs are still going strong and are not even bent after 250 km of 2 person rides at max speed.
If you inspect the design of the 2 drivetrains you will clearly see hobbywing is using the much stronger clamp design and lingyi is using the square fitting method also found on koowheel hubs, which is prone to get loose.
Hmm maybe I should just have someone fix my old Wowgo Mini, I have several sleeves laying around but it just stopped working after like 2 years of use.
I’d suggest picking up a Revel Kit, it’s a really solid board. Fits in your price range and it’s only 12 lbs, can go on most decks excluding drop decks!
Lol no why would I say I loved it if it was shitty
Range depends on rider weight and what wheels you select. But, the batteries are swappable. I’ve got three batteries and have never had a problem with range.
Speed, well you’re wrong again, you can go up to 30mph on it lol
