Sunday BMX Bikes: Common Questions
What Sunday BMX bikes are available at Urban Cycling Apparel?
Urban Cycling Apparel carries the Sunday BMX complete bike lineup from beginner to signature pro models. The Blueprint is Sunday's entry-level build using pro-style geometry with Odyssey Springfield brakes and an FSA integrated headset. The Primer ($489) steps up with a sealed rear cassette hub, Odyssey parts, and proven components like the Sunday Freeze stem across multiple top tube sizes. The Scout 21" ($559) is Sunday's mid-range all-around model. The Forecaster Park — Maca Perez Grasset signature uses 100% chromoly construction, Odyssey Gyro with M2 Trigger lever, and park-specific geometry loaded with Odyssey components throughout. The Street Sweeper — Jake Seeley signature features a 75.25-degree head tube angle, very short chainstay, Odyssey Clutch freecoaster, and left-hand drive setup for technical street riding. The Model C 24" ($669) extends the lineup to larger-wheeled riders who want park and trail capability at a scaled-up size.
What is Sunday BMX and what makes the brand significant?
Sunday Bikes was founded in 2005 and is a sister company to Odyssey BMX — one of the most respected parts brands in the sport. That relationship means Sunday completes ship loaded with genuine Odyssey aftermarket components rather than cheaper house-brand substitutes, which is unusual for complete bikes at most price points. Sunday is known for two proprietary engineering advances: Wave Tubing, which uses a rippled surface on the down tube and top tube to resist denting from rails, ledges, and impacts; and 41-Thermal heat treatment, a specialized process developed in-house that increases the tensile strength of the steel used in premium frames. These technologies address the most common failure points in BMX riding and have made Sunday a benchmark brand for riders who need their bikes to hold up to serious use.
What is the difference between the Sunday Blueprint and the Primer?
Both are beginner-to-intermediate bikes built on pro-level geometry, but they differ in component specification. The Blueprint is Sunday's most accessible entry point, built to get new riders on a properly proportioned bike with reliable parts like Odyssey Springfield brakes and an integrated headset. The Primer is a meaningful step up — it adds a fully sealed rear cassette hub, which provides smoother and more durable freewheeling action under hard riding, and uses slightly more refined parts throughout. The Primer is widely recognized in the BMX community as the benchmark complete bike in its price range. For a rider who is serious about progression beyond their first few months, the Primer's sealed rear hub alone is a practical reason to choose it over the Blueprint.
What is a freecoaster hub and why do some riders choose it over a cassette?
A standard BMX cassette hub engages immediately when you pedal forward and freewheels when you stop pedaling. A freecoaster hub allows the wheel to roll forward without the cranks turning — you can coast forward with your cranks stationary. This is a key technique for street riders because it allows specific tricks that require rolling forward without pedaling, particularly fakie-based moves where the rider rolls backward and then transitions forward. The Jake Seeley Street Sweeper signature comes with an Odyssey Clutch freecoaster as stock, which is a premium specification at the pro level. Freecoasters require more maintenance than cassettes and have a slightly delayed engagement when pedaling, which takes adjustment for riders not used to them. They are a street-specific tool rather than an all-around choice.
What is Wave Tubing on Sunday frames?
Wave Tubing is Sunday's proprietary tube design that features a rippled or corrugated surface on the down tube and top tube. The undulating shape significantly increases the tube's resistance to denting from rail and ledge impacts — the most common way BMX frames get damaged during street and park riding. A smooth round tube dents at the contact point when it hits a metal edge at speed. The corrugated shape distributes and absorbs that impact force across the tube's geometry rather than concentrating it at a single point. The result is a frame that holds up substantially longer under hard riding conditions without adding significant weight. Wave Tubing appears on Sunday's Soundwave and other mid-to-upper models in the lineup.
What is a 24-inch BMX bike and who is the Sunday Model C for?
A 24-inch BMX bike uses 24-inch wheels rather than the standard 20-inch, making it a larger, more stable platform that rolls faster and absorbs terrain more comfortably at the cost of being slightly heavier and less snappy for tricks. The Sunday Model C ($669) uses 20-inch-inspired geometry scaled to 24-inch wheels, giving it more familiar BMX handling than cruiser bikes from previous generations. It is popular among adult riders returning to BMX who want more comfort than a 20-inch provides, taller riders who feel cramped on standard sizing, and park and trail riders who want a fast-rolling setup for longer sessions. Urban Cycling Apparel ships all Sunday bikes direct across the U.S. from its Webb City, Missouri fulfillment center.
