DISCLAIMER ABOUT YEARS: The years that these bikes were released weren’t really designed to work in the standard format that people might be used to when it comes to organising bike releases. They were made and updated when they were done, it wasn’t really done to any schedule to have the bikes ready for a specific yearly release. The years have been loosely organised by collectors to make it easier for identification.

To make things a little more difficult, there were some minor changes made to the Big Daddy frames over the years, and it makes them a little difficult to categorise into years and models. So i’ll do my best.

The 1993 SE made Big Daddy  frame and fork set was the first model of the Kevin Jones Big Daddy frame that Hoffman Bikes released. It was designed by Kevin Jones and Brett Downs. The frame has a 1` headtube size, 3/8″ axle slots and the forks are 1″ threaded. Brett Downs wrote a really informative piece about the design of this frame back in 2015, and there’s really no better way for me to explain it, so I’m going to quote what he wrote, because it’s just the best insight into how this frame design came to be.

Quote Brett Downs: 2015

“When Kevin called me up to come over and design the Hoffman frame, we put a big piece of paper on his parents’ pool table, put a GT Pro freestyle tour frame on it, traced and then removed all but the head tube, BB and seat tube and dropouts. The reason is because at the time, the GT had the best geometry.

We took the Street Beat head tube gusett and elevated the down tube and made the gusset bigger. We love the RL-20’s oval down tube. Martin put a bigger top tube on the GHP Trix figuring you stand on it so we went with a 1 1/2″ top tube. GT had the best platform so we went with that, just angled the curve to the top tube more so it wouldn’t dig into your foot like a Trick Star. The 3/4″ stays were from the GT and also gave something more to stand on. The BB yoke was from the Supergoose. The rear brake bridge was square like the Dyno so if you wanted a caliper you could get it to seat and not crush the tube. The pierced top tube was from the GT. The 990 mounts were from the Haro because it was out of the way. We went back and forth with the coaster bracket location. So did the design.

We went with a 74.5 degree head tube angle because it felt great on the Trick Star. We went with a 70 degree seat tube because the CW was great for decades but too far back at 65 degrees. The Trick Star was around 73 degrees and felt too steep. It was definitely built with decades in mind.

The Big Daddy was a compilation of all the things we liked on all the different bikes. It didn’t just happen. It came from years of riding different frames and studying them. It wasn’t surprising it was a great frame. I think having Kevin and Mat’s names on them didn’t hurt sales either.

I’m very proud of my part in the design of that frame.”

So, the first Big Daddy was basically the offspring of a Trickstar, GT PFT, Street Beat, Supergoose and a GHP trix….

The first frames were available around October 1993. They were released in two colours only, chrome and dark green. They were available in a green and chrome frame and fork set, and there was also a number of chrome and green complete bikes made available.  It’s been confirmed by Mat Hoffman in his book that there was only 100 of these frame and forks made, i don’t know the numbers for how many got made into complete bikes and how many were sold as frame and fork only. I’m pretty sure that the number of complete bikes that got made for sale was pretty limited. I’m also unsure of how many of the frames/forks were green or chrome. I would say a 50/50 split maybe, but i base that on… well… nothing at all. Both colour schemes had the same flower design sticker set. The stickers were printed on a really crappy printer, and the inks rubbed off very easily. This is why when you see most pictures of the 93 Big Daddy frames from back in the day, the stickers are almost always rubbed off! Until around 2017, there was no good picture of the head tube sticker and it was really unknown what it even was, thankfully in 2017, a complete bike popped up with the head tube sticker fully intact and we were able to see exactly what it was!!

Here’s an original paint green frame and fork. (few sticker remnants on the frame, fork stickers still on there).

Original chrome frame and forks. (still has full sticker kit on F+F, they are partially rubbed off though.

When the frame was first released, it was covered in a number of magazines, and as a result we have a very good spec sheet about the frame. Here’s the specs of the 93 model from Feb 1994 BMX Plus.

Here’s another spec sheet form Ride BMX, this one has incorrect dropout thickness on it. The frame dropouts are NOT 1/4″ on the frame, they are 3/16″. They’re also not 1 piece, they are 2 piece squashed design.

There are 3 really easy methods to identify the 93 Big Daddy frames.

  1. All 1993 SE Big Daddy frames have two cable guides on the down tube. All later Big Daddy frame models only had one.
  2. The coaster brake tab is on the underside of the chainstay. Almost all of the later Big Daddy frames had the coaster brake tab moved to the underside of the seatstay. There was an exception of around 20 ramp room frames from 94 that had the coaster brake tab on the underside of the chainstay thought.
  3. Dropout thickness, all SE made Big Daddy frames have 3/16″ thick dropouts. All later Big Daddy frames have 1/4″ thick dropouts.

With the above 3 items, you can easily identify the SE made Big Daddy. I’ve seen frames with removed and added brake guides, i’ve also seen frames with removed coaster tabs and repainted… these mods can make it difficult to ID the frames correctly, but the dropout thickness is a very easy way to confirm the ID. All later models came with 1/4″ much thicker dropouts.

The original forks have curves in the legs, as opposed to the ramp room forks that have more of a kink. There are no markings on the fork steerer tube. When i say curved leg, i mean that the fork leg starts to curve as soon as it comes out from the steerer tube. On the later ramp room forks the tubing comes out straight from the steerer tube and then has a shark bend in it into another straight section. See the pic below, it will make more sense. 93 SE Big Daddy forks on the left 94/95/96 ramp room Big Daddy forks on the right.

The forks on the first Big Daddy model were curved as opposed to kinked like the following USA years. These frames have what’s known as the Marlboro wishbone where the chain stay meets the bottom bracket. It’s called that because it looks like a pack of Marlboro cigarettes due to its rectangle shape! They’re also described as having “pacman” dropouts due to the shape of the dropout looking a little like a pacman character. The dropouts on the 93 frames are 3/16″ thick, and there’s 2 cable guides on the down tube. The steerer tube on the forks, like the SE condor forks is a 2 piece design.
