The Compass

Monrovia, by bike.

Monrovia hands you a lot to explore, with roughly 68 miles of bike network stretched across hilly ground and a long, mild riding season. The catch is that the pieces don't yet link into low-stress routes, and the climbs ask something of you. Take it as a place with real reach for riders willing to work with the terrain and pick their lines.

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?
There are roughly 68 miles on the map, a substantial amount, but they don't yet knit into continuous, easy-to-follow routes. Closing those gaps is what would unlock the whole network.
Source · OpenStreetMap (Overpass): highway=cycleway/path
Calm Room to grow Growing
How much riding is away from fast traffic?
A fair bit of riding still runs alongside traffic, with separated space more the exception than the rule. Learning the quieter streets is well worth it here.
Source · OpenStreetMap (Overpass): highway=cycleway/path
All-Season Solid
How rideable is this place across weather and seasons?
The weather is a genuine strength, keeping the riding open for most of the year. Only the hottest late-summer weeks call for early starts.
Source · Open-Meteo (ERA5 climate reanalysis)
Welcoming Room to grow Growing
How easy is it for a newcomer or nervous rider to get started?
The hills are the real test for a newcomer, and the network doesn't yet offer many gentle, protected places to warm up. Begin on the flatter, calmer streets and build from short rides before you chase the climbs.
Source · Open-Meteo Elevation (Copernicus DEM); OpenStreetMap (Overpass): highway=cycleway/path
Room to Roam Room to grow Growing
How far can you genuinely go by bike?
With roughly 68 miles to draw on, the raw extent is here, though the hills and the missing links both temper how far a smooth ride goes. Ambitious riders will find room; casual ones will want to plan around the gaps.

Car-Light Room to grow Growing
How well can the bike replace car trips here?
Very few bike to work so far, which fits the climbs and the unfinished connections. Tie the network together and the everyday trips get a lot more doable.

Where Monrovia has the most room to grow

The two dimensions with the widest opening here — read as an invitation, not a verdict. Every one of these is something a resident can move, and none of it requires expertise or a fight.

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.

WelcomingGrowing · most room to grow

Welcoming grows person by person. Nearly every place has more riders in it than the streets suggest — coalitions, community shops, ride clubs, school runs — and they are the invitation.

Find the people already riding here, then bring one more person along.
