Sponsors: XRH, GC compound
Which size BMX did you start riding on: I started riding on a 16 inch BMX bike that my dad got for me when I was 8 and rode it till I snapped it in half. Then when I was 10 I bought a 20 inch BMX bike and have stayed on a 20 inch.
Do you have any advice for kids choosing a bike to start BMX? I definitely made the mistake of buying a bike that was too big for me so the best advice I could give would be to buy a bike that is the right size for you. It doesn’t have be a custom bike with expensive gear on it just something simple that you can learn on and progress on.
When do you think you will move up to a 20″ BMX? I have been riding a 20 inch for about 2 or 3 years now and I feel like it gives me a lot of room to move around on. I have never ridden an 18 inch because 20 inch bikes have always seemed more appealing to me with bigger wheels so I can get more speed for bigger tricks.
Favourite type of riding? (eg. park, street, trails, etc) I love to ride all types of style but I defiantly love to ride the GC compound which is a park setup. I do like to ride trails every now and then but there are not too many around where I live and street is fun and challenging for me which I like.

Any other special details or stories about your bike or parts? one little modification my Dad did for me was make a rubber washer out of a piece of the GC compound resi that goes between bottom bracket bearings and the bb spacer which stops the cranks from spinning which is really helpful in flip whips. Overall I love the way my bike is and every time I go to the skate park I look forward to riding it.

So you have a 20” BMX, but you are still riding your 18″. What made you decide to stick with the 18 for now? I have decided to stick with the 18″ for now because the 20″ is still a little too big. We increased the stem length on the 18″ and its just a better fit til I grow a few more inches.

Sunday Radocaster 18 Inch BMX Frame and Fork Test

BMX Groms Sunday Radocaster 18 inch BMX Frame and Fork Test and Review

The 18″ Sunday Radocaster is a unique frame and fork set offered by Sunday for the serious up-and-coming shredder. If you are into BMX and an average size 9 – 12 year old, this review is a “must read”.

This is the first year the Radocaster has been offered, so we were very interested to see what it would ride like. It features Sunday’s well thought out proportional frame geometry and slew of other features, such as:

  • Full chromoly throughout.
  • 8mm hollow dropouts.
  • Removable braking hardware.

Sunday build features like:

  • A miter cut top tube.
  • Reinforcing gusset at the down tube/head tube junction.

The fork:

  • One-piece, integrated-ready steerer tube.
  • Full-chromoly construction throughout.
  • Responsive 25mm fork rake.

At BMX Groms we were stoked to test an 18 inch frame where the company had seriously taken the time to consider every aspect of the frame including the geometry. Young riders are progressing quickly and companies are going to have to put the same amount the thought and design time into smaller frames, as they do into the common “20 inch” frames.

Bike Build and Finish

We had no problems building the frame and fork set up, all of our standard 18″ parts fit well. The frame uses a mid-bottom bracket and integrated headset. The finish looks good and the paint lasted well for our entire test which lasted for over a month. The frame comes in blue and the forks in black, unfortunately there are not other colour choices, but this is a higher end product for serious riders so we wouldn’t expect it to come in something like four colour choices.

BMX Groms Test

We choose two rad 11 year old BMX riders put the bike through some serious punishment.

Dorian Giordano, (Instagram: @dorian_bmx), was the smaller of the two riders. He regularly rides a 16″ BMX, so it was going to be interesting to see how he adapted to the larger 18″ Radocaster build. Unfortunately Dorian ended up with an injury just before our bike test, but he was still able to have a good session on the bike at Joyride 150 and give us some feedback. Dorian said the bike felt really good and that it was good for mannies, boxes and bike control and getting some nice height.

Nahum Billington, (Instagram: @chimpbmx), our other test rider usually rides an average geometry 18″ inch BMX. We were very interested to see how he adapted to Sunday’s proportional geometry. The Radocaster was a shorter frame overall, with a shorter rear triangle and a slightly longer top tube length. He adapted to the bike really quickly and on the first day was getting higher hops, better manuals, spins and learnt half cabs. In no time he was blasting 4 foot quarter pipe airs. When it came to hitting really large box jumps it took more of an adjustment, the shorter frame feeling more twitchy. However, at Joyride 150 Nahum found it easier to clear the box jumps on the Radocaster compared to his regular ride.

Nahum cranks an X-Up over a 7ft quarter on board the Sunday Radocaster 18" BMX Frame.

Here is what Nahum had to say about the Radocaster:

The Sunday Radocaster is a really awesome 18” bike. The Radocaster frame gives the rider a bit more support because it is full chromoly. The shorter rear triangle on the bike lets you pop up unto your manuals easier. You can also  hop higher on the bike. The Sunday was also really good on the box jumps. The frame gives a lot more bike control because it is more twichy. I find on the bike you can spin a lot faster, than the 18” inch frames with long rear triangles. The forks are nice because they are full chromoly tappered forks, which lets you rely on them more. The color blue on the Sunday Radocaster is a good color for the bike. I also like the design of the graphics on it. Overall the Sunday is an awesome bike for riders that want a good bike with the right geometry.

Sunday Radocaster BMX Review Comment

Should you buy the Radocaster?

If you are a rad 18″ BMX rider who really wants to progress you should definitely be taking a serious look at the Radocaster. We feel that for the majority of riders the geometry will help them to progress. We actually watched our test rider Nahum, progress significantly during the month of riding the bike. If you are an insane trails rider who hits pro size transitions you may feel more comfortable on a longer frame, depending on your size.

Priced at under $300 in the USA.
