Long Riders!, Amanchu! Recommendations
Amanchu and Long Riders share a similar scenario/plot and characters. In each our main character is learning something new and trying a new sport/hobby. Amanchu has diving and Long Riders is about cycling, the main character of each show is very new or never tried the new sport and has a friend to teach them everything there is to know while making new friends along the way. If you enjoyed the relaxed slice of life vibe from either show I would recommend the other.
