BMX Ramp Plans

BMX Ramp Plans

BMX ramp plans are an important part of bicycle races. They give the thrilling and exciting experience that the bicycle races are associated with.

BMX ramp plans should be ensure that the final product is able to achieve its purpose. That is to bring about thrill and excitement to both the spectators and the competitors. It should be able to test well the skill of the riders, their quickness and ability to handle the bike. The safety of the the competitors and the spectators should also be incorporated here.

You will need to choose one that suits you. This will depend on the kind of tricks that you may want to perform. These plans can be available on specific sites on the Internet either for you to download freely or to purchase.

These kind of sketches will enable you to construct a slope successfully. They will give a rough diagram of the intended slope, the dimensions and materials that will be required. They will give a step by step guide on how to build the slopes, what to avoid such as stone and leaves, and what not to forget like testing the durability of the slope. They will also show what material to put where and in what quantities. They will enable you to budget carefully and work according to the budget and schedule.

Bike Fit

Bike Fit

Make the bike fit your body.

Measuring you and your bike to do the right bike fit adjustments:

Measure the length of your inseam to the floor with bare feet placed 15 cm apart.

• Bike Fit for Road Bicycle / Road Racing Bicycle: Multiply your inseam with 0.61


• Bike Fit for Normal Bicycle / Utility bicycle: Multiply your inseam with 0.64

The result is a bike fit recommended size of a road frame to you, measured from the centre of the crank to the joint of the saddle tube at the joint of the saddle and top tube. This calculation is based on the top tube to be horizontal.

Some frame and bike manufacturers give you the size of the frame measured from

• the middle of the crank to top of the saddle tube or


• the middle of the crank to middle of the joint of top and the saddle tube or


• the middle of the crank to top of the top tube at the middle of the saddle tube

This can be confusing and make your bike fit adjustments to a complicated thing. The result of the measurements you got from this guide do not lie. Call the bike shop and ask the size of the bike you consider to buy and tell them to go measure from middle of the crank to the middle of the joint of top and saddle tube . Even better measure the size as described above yourself.

If your current or your desired frame has a sloping top tube you should measure starting the anchor point from the middle of the front tube at the joint of the front and top tube to the middle of the saddle tube in a horizontal line. Mark the point at the middle of the saddle tube with tape. Measure from this point to the middle of the crank.

The Bike Saddle Height must Fit to your Inseam Length:

You can find different methods to calculate this crucial distance. You might need a friend to help your with all the measuring.

Begin the by standing on a hard surface with your (cycling) shoes on and your feet about 15 cm apart. Use tape to help you and measure from the floor to your inseam and push with the same force as a saddle does. Multiply this figure by 0.883. The result is your saddle height, measured from the centre of the crank axle along the middle of the saddle tube to the top of the saddle.

Add 2 or 3 mm if you have long legs compared to your height. If you suffer from knee pain caused by damage to the back side of the kneecap adjust the saddle a bit higher. But the saddle height should never be so high that your hips bobbing over the saddle when pedalling around. If this bike fit formula results in a big change from your current settings you must move your saddle 2-3 mm per week until you reach the new position on your bike.

If the top tube is horizontal you can do a double check to make it fit your inseam. The distance from the top of the saddle tube up to the saddle should be about 12-15 cm when the saddle is set at the correct height. When the crank arms are horizontal and you have clicked into the pedals wearing cycling shoes your knees should be at the top tube of the bike when you squeeze them together and the pedal shaft should be in a vertical line below your knees. Then you know you got the right fit for your bike.

This bike fit recommendations to the saddle height is based on a crank arm length of 170 mm. Adjust your saddle height in relation to whether you are using longer or shorter crank arms than the 170 mm which this calculation is based on.

Length of Crank Arms is important when dealing with bike fit:

Based on the length of your inseam you should choose the correct length of the crank arms.

Follow these bike fit recommendations to the length of the crank arms:

• Inseam less than 69 cm, use 165 mm crank arms


• Inseam between 70-82 cm, 170 mm crank arms


• Inseam between 83-86 cm and 172.5 mm crank arms


• Inseam longer than 86 cm, 175 mm crank arms

The length of a crank arm is measured from the centre of the crank fixing bolt to the centre of the pedal fixing hole. The length is usually stamped on the back of the crank arm. If you use the crank arms longer than recommended you will be able to pedalling at higher gears, but will lose the speed of your pedalling. In some cases the large gears can course injuries to your knees. With shorter crank arms you will improve your short sprint skills and loose a little to your top speed.
