I received my Nikola 100 V 1800Wh 21700 wheel about 10 days ago. I am thoroughly impressed! I opened up this Nikola to check the internals. The batteries, connection and wiring were well secured. The materials looked of good quality too. This Nikola is fast, nimble and has amazing range. Coming from 2 King Song wheels (KS14C and KS18L), you have to get used to the riding dynamics of this wheel. I reached out to veteran Nikola riders how they tamed this wild beast. I then applied their advice and by the next ride, the wobbles disappeared. It is definitely a unique wheel. She is a beast that needs to be treated properly and in return, she will give you the ride of your life! What an awesome wheel!
