Stephen Curry chalked up an L Thursday before the Warriors took on the Spurs ... getting his butt kicked in a ScootEBike race ... and TMZ Sports has the footage.
It all went down in NorCal ... a rep for Raytroniks (the company behind the bike) says they sent a street team to gift the $1,600 electronic bikes to Steph and Ayesha Curry.
BTW, the bikes can get up to 20 mph ... they're kinda like the next iteration of those hoverboards.
We're told Draymond Green also got one last night ... so ... teammate race???
