A few others on ebay right now have these serial numbers, 011500 which the seller says is a Jan. 1981 frame, another serial 13449 is being sold as a 1981 because the first number is a 1, while another one with serial 1121581 I believe is being listed as a Nov. This dyno is great tool for motor analysis, ESC (boost) adjustment, brushless sensor adjustment, gearing calculation, etc. The dyno is coupled to a m This is a universal benchtop inertia motor dynamometer (dyno) that measures the rpm, Kv (rpm/voltage), voltage, current draw, power and torque output of a electric motor.

Hi guys,
I happened to see this bike on eBay a bit ago and the seller had it advertised as an '89 Dyno Compe Survivor' based on the serial number on the dropout he was able to read. Upon looking at his pictures, I could instantly tell that it appeared to actually be a '90' model instead because of the decal set and the straight forks Dyno went to beginning in 1990.
When I looked at the serial number in the picture, is where I started to get really confused. It shows 'DH8912XXX'. Is it then really a 1989 model as he states? Or a 1991 because of the '91'? I know Dyno didn't switch to the cutout/flare-back drop out (and again to the straight forks) until the 90s which would make this a 1990 at the earliest. I know there are those who will say you can see this type of drop out in the '89 Catalog, but as far as hitting the showrooms, I don't think these appeared in their Production bikes until the 90s. Dyno switched decaling in 1991 as well, with 'Dyno' and 'Compe' literally switching places on the bars.
Then I went to my storage shed and pulled out two old Dyno frames I've had for a while, and the same debate continues on these as well. I have an original 1987 Dyno Detour and a 1988 Dyno Compe. These are both factory original and have not ever been repainted or redecaled.
To prove these are structurally different frames, I illustrate in this next picture where I've laid the smaller 1987 frame over top of the 1988 frame. You can see that the blue frame is about an inch higher in the back tubing as this was changed from '87 to '88.
You can also see in this picture that the support plates around the seat tube on the 1987 Detour are completely open (basically two separate 'Dyno' stamped plates, one turned upside-down and welded opposite, hence the logo on the bottom side too). On the 1988 Compe it's one solid piece bent back on itself with two holes drilled out for brake cables.
The difference in the rear of the frames are illustrated here. From the bend at the top of the rear tubes above where the rear brake mounts, is an entire inch different between the '87 and '88.
So now here's where it gets weird. It may be hard to read, but the serial number for the 1987 Dyno Detour on the left is [DH8873426] and the serial number for the 1988 Dyno Compe on the right is [DH8803278]. Also notice that the '87 drop out doesn't have the Dyno 'D' stamped in it, but the '88 does (another physical feature that began to surface in 1988 distinguishing any previous models).
So here's the debate... the black bike decaled as a 1987 DOES have '87' in the serial number at positions 4 and 5. However, with that same logic, then the blue bike decaled as a 1988 would be an '80' model. If you base it on positions 3 and 4, then they would both be '88's (which they're clearly not) and making the chrome bike at the top an '89'. Three separate bikes, three totally different designs, structures, and decals... yet no clear logic to the numbers.
Any one have any input on this? I think it's up for debate on how to read these serial numbers and/or even if they matter if there's no consistency.

Dyno MoonEyes – this is a beautiful and distinctive bicycle, in part because of the yellow and black color theme! The MoonEyes uses the Dyno Glide non-gusset frame, the 1″ threadless triple tree forks and a MoonEyes branded chainring. The handlebars are the wide rounded type mounted with the GT piston type stem. The kickstand is mounted on the bottom bracket shell. The wheels are 26″ front and back. And a really tricked out MoonEyes may come with disc wheel covers.
Dyno Compe Serial Numbers
Early Dyno’s came with a D on the back of the top tube just behind the seat post – until 1999-2000. Later bikes had the Dyno Headbadge and a Dyno decal on the seat tube.

After GT, which bought the Dyno franchise from Morales, went bankrupt, Pacific Bike Company ended up with the Dyno name. Dyno’s were then sold as Kustom Kruzers. It is said that the early KK’s were OK but after a short while, the quality went downhill fast.
