"Lemon" Bike???
Most of us have probably experienced owning a "lemon", most
likely a car, but they come in other products as well. Can't say I've ever heard of a lemon bike though? Anyone ever own a lemon bike? [I know some will be tempted to call a *Mart bike a lemon by definition, but a cheap or inexpensive product is not necessarily a lemon.] SMH |

My very first mountain bike -- a $1200 Gary Fisher Paragon (1996) -- had all sorts of strange problems from day one. Terrible shifting, breaking chains and cables, etc. Finally one day I was climbing a short hill and the rear derailleur completely disintegrated! I had to walk it home (didn't know any better back then) and went straight to the LBS still bloody and sweaty and dirty and demanded my money back. Instead they agreed to replace the frame. Apaprently the first one was enough out of alignment to mess everything up. (The new frame cracked eventually; still have an almost new warranty replacement Paragon, as I went full suspension around that time.) Then just recently I bought a Madone SL "frameset" (frame & fork & seatpost clamp), and the rear dropouts were so crooked it was obvious right from the first wheel install. Even the less-than-helpful (kind terms) store manager had to grudgingly admit it was twisted, and gave me a new one. (Suddenly they had /plenty/ in the back, even though they acted like the first one was the ONLY one left in my size.) It's been fine...although a PITA to dial in (my fault for buying a "micro-adjust" seatpost -- I'm literally inbetween grooves! Story of my life ) So yes, bikes can be lemons. Now let me tell you about my brand-new CAR... (SIGH!) Bill S. |

oh yes *mart bikes are DEFINITELY lemons...
...."when is cheap TOO cheap?" example: the one piece crank on this generic *mart ATB I had come into the shop recently. In decent shape otherwise, the owner was complaining that the chainrings weren't moving while the pedals were. Normal one piece crank is cast & machined. There is a little "peg" cast into the crank that engages a hole on the el cheapo sheet steel chainrings and turns them. There are no keys/channels cut into the chainrings or the crankshaft...it's all accomplished with that one peg. This one-piece was NOT cast...it was a machined and bent piece of barstock. The peg? 'Twas a small chunk of the same barstock...welded onto the RH crank with a resistance welder. Of course, it failed... This kind of crap design is ok for kiddie bikes, but for a 200lb rider with a little "heft" in his legs, that peg is gonna pop off like a champagne cork. B.

Can't say I've ever heard of a lemon bike though? Anyone ever own a lemon bike? [I know some will be tempted to call a *Mart bike a lemon by definition, but a cheap or inexpensive product is not necessarily a lemon.] SMH I had a fulll suspension ATB that I had bought years ago at the LBS. It was a mid level bike, not an entry level model. After a couple of weeks, it got to where it would never quite shift right. On the three of the most common to pedal on gears (for me at least), it would jump back and forth and never just stay on the gear. I had taken it to the shop twice and they never could get it to work right. Later the shop went out of business, and so I took it to a different shop and paid to have it worked on. They replaced the cables and tuned it up pretty good. But sure enough it still had that stupid jumping around on the gears shifting problem. It appears to work fine in the shop on a stand, but when you go to ride it around, the rear shock compresses a little and apparently that changed the frame geometry just enough to screw up the shifting somehow. Eventually I wound up selling it at a garage sale for super cheap next to nothing, as I could never ride it with the gears jumping like that. I have messed with a super cheap folding bike from a big discount store chain. The bike works OK, but the frame isn't straight, as you sort of ride down the road sideways a little. The bike tends to pull to the right if you let off the handlebars. When you are riding the bike, you can see the front wheel is angled to the left a little, about 3/8" ro 1/2 of an inch when you are going straight. I even tried obnoxiously angling the rear wheel all the way over to one side almost rubbing on the frame chain stays and it still tends to ride down the road a little sideways. |

This kind of crap design is ok for kiddie bikes, but for a 200lb rider with a little "heft" in his legs, that peg is gonna pop off like a champagne cork. From experience assembling and inspecting a pile of bikes equipped with those last year, I will add that the type of crank in question isn't so much machined as it is bent and hammered. The flats for the pedals are produced by just severely flattening the end of the rod, probably done cold, most likely with a trip hammer. If the hole is punched[1] a bit too close to the shoulder, there is a tendency for the tab to fail when the pedal is properly tightened; it rips open from the corner of the tab to the hole. It doesn't even require the weight of a rider for these to go south; just putting the damnthing together can break it. [1] Drilled? Don't make me laugh. No, it was *punched*. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts. |

That is interesting, too late for me now, but I'll definitely keep it in mind the next time I run into it. Thanks |
