Insight help needed for collecting electronic parts RW4

[stefaan]

Hi everyone!

I am a double sided happy as a bit frustrated user of my Radwagon 4 bicycle purchased in 2022.
Since i am living in Belgium and saw in the same year the European branch of RadPower making a retreat, i am trying to get a hold on the idea to collect the essential electronic spare parts of RW4 to extend the lifespan of my bike when the supply will stop. This will likely happen in the near future when the last warranties will expire in Europe. Because of the massive work and reliability ( outside of some minor points with a battery problem ) it performed already, i found the idea to store some essentials compelling enough to buy from time to time achievable parts. So far I already detained throttle and rear wheel motor hub set already. Anything besides the mechanical parts that seem to be generic to be replaced. Is there any advice if i should continue to purchase definitely some parts from the manufacture RP itself? I had my eye on my last wish list adding a controller and display to be safe. I hope somebody can raise some enlighted answers what ether the idea itself is more sustainable than the bike itself or that i can keep working around the iron frame with generic gear from other companies.
Thank you for your help!!
