Description
K-18 MTB-oikaisu is a very short point-to-point mountain-bike connector—about 1 km on our map—in the Kytäjä–Usmi recreation forests west of Hyvinkää. It threads the same forest-road and path mesh as the city’s three signposted MTB loops (Karhujen, Kytömetsän, and Hyvinkään pyörähdys), so it works best as a cut-through when you are linking those circuits or approaching lakeside rest spots instead of riding the longer way around.
The line sits in the Natura 2000 woodland between the Iso-Karhun campfire cluster and Kaksoslammien laavu, then carries on toward Latu-Miilun maja at the northern end: you pass the Kaksoslammet lean-to a few hundred metres after the start of this segment, and the ski-club cabin setting at Latu-Miilun maja sits just past the mapped finish—handy for combining with Karhujen pyörähdys, Kolmen lammen kierros on foot, or the Usmi ski loop in winter. City materials do not give this exact connector its own trail page; for how the wider MTB network is marked and managed, start from the City of Hyvinkää’s mountain-biking hub and the Karhujen pyörähdys trail page, which describe bear-on-blue waymarks, counter-clockwise looping, gravel-leaning surfaces, and parking at Usmi beach. The same network is mirrored on Luontoon.fi for map browsing. The Kytäjä–Usmi outdoor area overview lists roughly 27 km of maintained MTB lines and the mix of lean-tos, dry toilets, and firewood policy across the wider trail system—expect similar etiquette on connectors.
Experienced riders threading a longer tour through Usmi often stage from Hyvinkää station or Sveitsi, roll toward Iso-Karhu, and shape loops toward Kiiskilampi or Petkelsuo; one detailed Jälki.fi write-up notes varied forest path with short technical pitches near Iso-Karhu before continuing toward Kiiskilampi and Kaksoslammet—useful pacing context for how this terrain feels even on a kilometre-long link. For fat bikes, e-MTBs, or gravel rigs without your own transport, Sveitsi Rent at Hyvinkää’s Sveitsi sports cluster takes online bookings and highlights the area’s ride network.
Hyvinkää lies in Uusimaa inland from Helsinki; treat this connector like any other forest tyre track—yield to hikers where tread is shared, carry out litter, and confirm campfire rules when warnings apply.
Length & route
The mapped line is about 1.0 km point-to-point. Official pages describe the overlapping Karhujen pyörähdys loop at 11.4 km with roughly 114 m ascent and a mix of paved road, gravel, and softer forest tread—useful background for surface expectations nearby.
Getting there
Most riders reach this mesh from the Usmi beach parking at Usminjärventie 206, where Karhujen pyörähdys posts begin, or by joining from other Kytäjä–Usmi trails such as Kolmen lammen kierros or Mustan kiven kierros at shared lean-tos. Digital GPX layers and printed outdoor-theme maps are available from the city’s maps pages. Sveitsi Rent stages rides from the Sveitsi area if you need a local bike.
Good to know
Kytäjä–Usmi is part of a Natura 2000 site with private nature reserves and Metsähallitus stewardship—stick to public outdoor corridors and respect wildlife. Firewood maintenance is guaranteed only in the snow-free season per the city overview. Mobile coverage is generally good except in the deepest dips.
Where to rent bikes
Sveitsi Rent (Teerimäenkatu 6 / Sveitsin Uimala, Hyvinkää) books fat bikes, e-MTBs, gravel bikes, and children’s fat bikes through its Johku rental desk; the shop promotes the Kytäjä–Usmi ride network from Hyvinkää’s Sveitsi area.
Guided tours & Experiences
Sveitsi Rent lists year-round guided outdoor programmes for groups and individuals from the Sveitsi base and broader southern Finland.
Ride either way as a connector; the main Karhujen pyörähdys loop is described for counter-clockwise travel.

1 km
Distance
Often well under half an hour of riding for the kilometre alone; budget more if you stop at Kaksoslammien laavu or Latu-Miilun maja.
Est. Time
Expect the same compacted forest roads and softer tread called out for Karhujen pyörähdys nearby—paved connectors near parking, gravel and “other” forest surfaces deeper in the woods.
