Very possible. It hadn't been wet in a while, but it was definitely treated poorly before I converted it to electric.
Yep, bought all the parts separately online and converted an old longboard.
I'm still quite new to eskates (and skateboards in general) so I'm not the best person to give advice, but here's what I've figured. It seems like building your own is generally more expensive than buying a prebuilt board. However, the prebuilt boards may have less swappable parts, which make it harder to maintain, repair, or upgrade. To be honest, I never really considered a prebuilt board because I wanted to have the learning experience of building my own. For me the build process was relatively plug and play, besides soldering new connectors on my motor wires, drilling holes through my deck, and carving the sides of my deck to allow for the bigger wheels. If you're thinking about building your own, google is your friend. There are a lot of online blogs and forums that can help you. I suggest you plan everything before your buy anything to make sure all your parts will work together.
More pictures of the aftermath. Nothing besides the deck is broken
Yes, I had carved pieces off the side of the deck to allow for the huge wheels. Definitely broke at the skinniest spot.
Yeah, I only built it about a month ago, but the deck was super old and neglected. Was planning on getting a new one, but ended up keeping this one because it worked. I liked how it looked kinda crappy but could go pretty fast. sleeper longboard lol
Hit a small lip where the asphalt turned to cement and my board snapped
That's amazing! I'm gonna set it up on my instance
