In 1989 mountain bikes was the New and Hot. I got my first one in 1989. A purple CyclePro. Although that is of course personal to me, it is a very typical bike, and they came along the same insane colour schemes as skis, and skiing clothes so well presented in GZ.
Road bikes with thin wheels was also a Thing. (I traded my really crappy MTB for Crescent road bike after a year!!!)
Those who were too lazy to ride bikes, got a moped (“moppe”), in Sweden more specifically a Yamaha DT, 50ccm. They were limited to 30km/h, but by removing all the innards of the muffler, you could get a few km/h more, and by tweaking even more, you could make it go 50-60km/h. However, they were noise as hell!
My suggestions :
- Make these bikes/moped several crowns and not easily available
- Introduce an MTB, in horrible colours (authentic 1988 suggestions below), that are not fast, but move a little better in terrain.
- Introduce a road bike, that’s faster than the other bikes, but only rideable on paved roads. Make you fall off the second you leave the road!
- Introduce the Yamaha DT, make it slightly faster than the bikes, but really really noisy, so it attracts machines
