The Compass

Marshalltown, by bike.

Marshalltown sits amid the gentle farmland of central Iowa, on ground that asks little of a rider's legs. A mapped network of roughly 17 miles is already in place, a real foundation even before it adds up to connected, end-to-end routes. The climate holds up well too, with a long comfortable season from spring through fall and a clearly defined winter to plan around. Where Marshalltown still has room to grow is in stitching that network together, calming the streets around faster traffic, giving a new rider an obvious place to start, and making the bike a normal way to get somewhere -- all genuine opportunities, not marks against the town.

The six dimensions

Read it dimension by dimension

Tap a dimension to jump to it.
Connected Room to grow Growing
Does the network join up into usable routes?
Marshalltown's roughly 17 miles of mapped network gives a rider real pieces to work with, even if they don't yet add up to a single usable route across town. Connecting those pieces, rather than adding more mileage, is what would change daily riding most. It's a clear and specific opportunity.
Source · OpenStreetMap (Overpass): highway=cycleway/path
Calm Room to grow Growing
How much riding is away from fast traffic?
On gentle, level ground, calm riding in Marshalltown currently comes down to choosing the right residential streets rather than following a dedicated low-traffic route. There isn't yet a mapped way to avoid faster roads by design. That's the opportunity: the flat, easy land is already doing half the work.
Source · OpenStreetMap (Overpass): highway=cycleway/path
All-Season Solid
How rideable is this place across weather and seasons?
Marshalltown's climate is a genuine strength: the good-weather season runs long, spring through fall, and winter is a defined stretch rather than an open-ended one. That's an asset the town already has, independent of any future paving or planning.
Source · Open-Meteo (ERA5 climate reanalysis)
Welcoming Room to grow Growing
How easy is it for a newcomer or nervous rider to get started?
Gentle terrain makes Marshalltown physically approachable for a new rider, but there isn't yet an obvious low-stress route to hand someone just starting out. The roughly 17 miles of network is real, but it hasn't yet become a clear welcome mat. That gap is the opportunity.

Room to Roam Room to grow Growing
How far can you genuinely go by bike?
The flat farmland around Marshalltown would support real distance riding, and the roughly 17 miles of mapped network is a start, but going far today still means relying on ordinary roads to connect the pieces. More connection, not more distance, is the growth path here.
Source · OpenStreetMap (Overpass): highway=cycleway/path; Open-Meteo Elevation (Copernicus DEM)
Car-Light Room to grow Growing
How well can the bike replace car trips here?
Only a very small share of Marshalltown commuters bike to work today. Gentle terrain and a cooperative climate are real advantages already in place. What's missing is the everyday, connected infrastructure that would make the bike a normal option for routine trips rather than an exception.

Car-LightGrowing · most room to grow

Car-light is a habit before it’s a statistic. Every ordinary errand made by bike makes the next one likelier — for you, and for the neighbor who sees it and thinks, I could do that.

Ride the ordinary trips, bring somebody with you, and have the numbers ready when someone asks.
