Bicycle mechanics

Before leaving for France, I got a wild hair and decided to attempt some bicycle maintenance on my Batavus. There’s no Batavus dealer in my area, and I was a little bit worried that no one had checked in on the internal hub after a year of riding, even though I haven’t had any problems. So I grabbed up my manual, thinking, there’s got to be something I can do in here...

And there was. According to my manual, the gear shift unit was supposed to have two red dots on it that needed to be aligned—if they weren’t, then the gears were “out of tune” (I can hear you actual bicycle mechanics laughing their asses off all the way in France—maybe one day I’ll master the lingo!).


Luckily I had a faithful assistant at my side.


he already has grease on his nose!

I looked for the dots in the location the manual indicated. Didn’t see them.

My assistant took a turn. Still no dice.


Finally, after rolling around a bit and craning my neck, I noticed the red dots—BELOW the gear shift unit, not to the rear of it. Possibly this has to do with some adjustment they made to the bike in Littlehampton, to make it better for hills. Or possibly my Bat is a mutant. Opinions?

Either way, they were found, and adjusted (very slightly), and we all lived happily ever after. I thought this might be useful to other mechanic dilettantes who don’t have a Batavus dealer nearby!

Have you ever found that something on your bike was different from what was shown in the manual?

    I don’t know a lot about bicycle maintenance, but your assistant is certainly the sweetest!

    love your friend…and was that “still no dice” or should it have been”still no mice” :D

    The indicators are on the bottom of my IGH too.
    My furry assistant has learned that I make too many strange sounds to be trusted when I’m working on bikes, and he confines his assistance to cleanup when I’m cooking and lap blanket when I’m sitting.

    I didn’t realize bikes came with manuals… but I’ve never purchased a new bike before. The ones you pull out of dumpsters don’t usually come with manuals.

    How do you make bicycle maintenance look so cute?!

    Trisha, first off, can I just say how much I love your little assistant? So cute! I love the picture of him (her?) checking out the bike hub.

    And second, good for you for taking the manual out and figuring this out on your own. I have a natural aversion to instruction manuals of any kind but find that when I get over than, the knowledge gained by reading one can be quite useful.

    Hope you’re enjoying France!

      He! I can’t believe I didn’t give Walter more credit. I come from a long line of manual readers — when I bought my car from my dad in high school, he made me read the whole manual before turning over the payment book. :)

    My bicycle manual, doesn’t even give that much information. It doesn’t describe the removal of the front brake cable, or how you would remove the chain guard or, basically ANYTHING to do with changing a tire, or other maintenance or service. It’s occupied solely with warnings on what NOT to do, and nothing about what you should do (Don’t stand on your head while riding a bicycle, don’t spit on the sidewalk while riding a bicycle, don’t swallow grape seeds while riding a bicycle). It also states that the bike has a Sturmy Archer 3 Speed, when in fact it actually has a Shimano 3 Speed.

    You want information, you need to look up information online, about repair and maintenance of the Shimano hub, repair, removal, adjustment of the front (Roller) brake cable and minor details like that.

    Mine has no useful information at all. Just a spot to write down the serial number of the bike, on the cover.

    I’ve seen internally geared hubs with two sets of dots – it messed me up a little the second time I adjusted it because I was sure that the markings were in a different place the first time. For anyone making this adjustment at home, remember to put the bike in the neutral gear (4th on 7 & 8 speed shimano hubs) before adjusting the cable tension with the adjuster barrel. The only other maintenance these hubs need is an overhaul every 10000-15000km (a completely maintenance free bike is a disposable bike).
    Also, I love your helper! I’ve got a couple of furry helpers too, but they’re most interested in batting nuts & bolts & valve caps under the couch.

  9. love your assistant. furry friends certainly do make these weird tasks a little easier.

    Your Batavus came with a manual? I hope my Breukelen comes with one when I pick it up in a few weeks!

    Thanks for saving me the trouble researching how to adjust a Shimano Nexus hub ;-)

    Furry assistants are great…most of the time.

    I had one that like to lie on my work bench, I had to make sure I covered up stuff. On one occasion I was missing a couple of bearings, apparently they stuck to her when she laid on the tray.

    There’re two GREEN dots on my internal gear hub. I didn’t know about them for a while and my shifting was wonky. I waslked into the bike shop and they said, “oh, put it in gear 4 (the marked one) and turn the dial until the dots match.”
