Roller Derby Intruder Kick Scooter Review

Roller Derby Intruder Kick Scooter Review

>>  I rode an inexpensive Fuzion City-Glide kick scooter for more than a year, even though it was wobbly all over. Fortunately, many of its design flaws have been fixed in a new model, but rather than replacing my old City-Glide with a new version, I went shopping for a kick scooter that was much tighter.

What I found to replace it with was the very reasonably-priced, "Roller Derby Intruder." It has no folding mechanism at all, but in its place, there is a non-extendable, removable steering tube, large 200 mm (8-inch) wheels, and a wide, long, low deck.


  • Rider weight limit: 100 kg (220 pounds)
  • Handlebar height from ground: 99 cm (39-inches) (see comments below)
  • Handlebar width: 44 cm (17.5-inches)
  • Height to the top of deck from the ground: 7 cm (2.75-inches)
  • Distance to the bottom deck from the ground: 4.8 cm (1.9-inches)
  • Usable deck length (head tube to brake): 35.6 cm (14-inches)
  • Maximum deck width: 15 cm (6-inches)
  • Wheel base (axle to axle): 70 cm (27.5-inches)


My first impression of the Roller Derby Intruder was "this is perfect!"

It is built solidly like a trick scooter (which must be sturdy), but with large wheels. The deck feels solid, like it is welded on to the handlebar, which it is! Riding it makes me feel very much in control of the scooter's behavior because of its solid construction and wide handlebar. Without all the handlebar wiggling, its solid construction allows me to put more force on the bar when I kick and my front wheel doesn't lift off the ground.

The deck is low, as recommended by the folks at LetsKickScoot.com. So low, in fact, that I don't have to bend my standing leg when kicking.

The deck is also relatively long and about the same length as the City-Glide's, both of which accommodate my size 11 men's shoes.

I also like the deck's width. It is wide enough to put my feet parallel to one another, although I personally do not stand this way.

The scooter has a very sturdy brake that features two contact points. Out of the box, the second contact only touches the wheel when you press down very hard, nevertheless, even with one contact making a solid hit, the brake works better than the fender-style brake of a City-Glide. I had the pleasure of owning two Roller Derby Intruders by now (if you "found" my two-week-old scooter on the train in Philly, shame on you!). The build quality on both is excellent.

The handlebar does not fold, but it can be easily removed. The handlebar is held in place with a clip and a push-in pin arrangement. Taking it off reveals a 9 cm (3.5-inch) head tube. Disassembled, the scooter is easy to carry and small enough to take on a train or in a car.

Assembling and disassembling is easy: open the clip, push in the pin, and slide out the bar. The pin keeps the handlebar aligned with the wheel.


The handlebar is not adjustable.

I am 6-feet, 2-inches and at first, I thought the bar height was OK, although it was about 2.5 cm (1-inch) shorter than the City-Glide's.

After riding for a while, I noticed that the shorter bar height caused me to bend my standing leg much more, which strained it. I found that by not inserting the handlebar completely (and not using the push-pin), another inch of length is gained. So far, I've had no problem with that arrangement, but recently, I extended the handlebar another 5 cm (2-inches) by using a quill extender for bikes. The longer handlebar is now is perfect for me and it is higher than on any other scooter I've ridden.

The grips are more sturdy than the normal, inexpensive, foam stuff, but are very hard and transmitted a lot of vibration. I replaced them with silicon grips (ESI Chunky Silicone). Perfect!

The bearings... oh cr**! Just giving them a fancy name (Bevo Gold-7 Race Rated) does not mean they are good. In fact, they are horrible and vibrate at high speeds. After two weeks or so of riding, they do wear in, but they are not perfect and cause the scooter to lose its scoot. After enough irritation, I replaced them with Magic Race Bearings.

Unfortunately, the decals on the Roller Derby Intruder try too hard to be teenage-cool. Fortunately, the decals come off easily.

On my current Roller Derby Intruder, there is a slight problem with the second brake contact point, but it works OK "as is" out-of-the-box, so I have not adjusted it. My first scooter (the one I left on the train) required some filing and bending to improve contact. Should you buy a Roller Derby Intruder, be aware of this potential problem. The brake itself is spring-loaded and makes a clicking noise when going over sidewalk joints. Noise aside, I prefer it to fender-style brakes.


Overall, this is a very decent and inexpensive adult scooter. More to the point, I believe that it is probably one of the most sturdy on the market today. If you are not over 6-feet tall and are willing to invest in new grips and possibly bearings, and can live without a folding mechanism, this is the scooter for you! It is also the scooter for you if you are just sick of the twisting and wobbling, flinching and crunching of your folding scooter. If you are over 6-feet, however, follow my instructions for lengthening the handlebar.

A similar design, but with a great folding mechanism is the Crisp Big Wheel Commuter. It is, however, more than double the price.

The picture above shows the handlebar taken off with the original handgrips still attached. The silver piece in the stem is the quill extender I installed. It provides a very tight fit.
