Maple Taba Bike ride Nakatsu Kyushu

Has anyone any details about this interesting-looking bicycle route from Nakatsu - apparently along an abandoned railway line? Some details are on the net but not how to contact and ask questions about how to find it, maps and details and where to get bikes etc. . We will be in the area in March and would love to take it.....and some other interesting and not too challenging short rides in Kyushu

Thank you. We are hoping to get an email contact for a rental bike shop so we can be sure before we drive there. Phone calls may find people without English. I suppose we can just turn up and take our chances.
Is it clear if we should go to the Nakatsu Station first or just go to the bike shop which seems some distance away?

I did a search for "Yaba-kei Cycling Terminal" which bought up some useful links. One of which lead me here https://www.city-nakatsu.jp/kankodocs/2014022100011/ That page has an email address which you might try It's E-Mail：yb-chiiki@city.nakatsu.lg.jp I hope this helps

Thank you. I just had an email from that address and it included an English version of the route map, which is usefull but we still can't contact the bike shops about renting bikes. I have asked the manager of the guesthouse we have booked in Nakatsu (who speaks English) if he could kindly check on the bike details for us. From what I can make out, we can drop off the bikes at the far end , but how we get back to Nakatsu is not clear?
