Why do I keep going down?

10804 Views 124 Replies 48 Participants Last post by  Misti
Well I did it again tonight! I fell down for my 8th time now!!! I’ve only been riding for maybe 6 months or so and have fallen down 8 times now and I can’t figure out why I keep falling? I feel like I’m a good rider I really do but for some reason I keep falling down.! Tonight I was driving around a gas station store and a car came around the other side kinda fast so I guess I pulled the front break while making the turn and like always I was on the ground! I must have the best luck ever because I have never been seriously injured actually in all but one of my falls I’ve jumped back up and rode off with out a scratch on my body! I’m just confused on why I keep falling down? If anyone has any ideas on why I’d love to hear them. Thanks in advance!

It's not front-wheel locking that's problem, it's how it's applied. Most beginners panic, grab both-brakes as hard as they can and end up locking both. Proper procedure is to apply both and gradually increase force. Then as rear lifts due to weight-transfer, let up on rear (or leave it locked as trained in beginner crashes).

In vast majority of crashes where auto cuts in front of rider's path, there's LONG skid-mark of rear locked-up tyre leading right into crash! If they had properly used front-brake only, they would've stopped in plenty of time.

Imagine an invisible-hand pushing back on bike to decelerate. This braking-force is applied at tyre's contact patches. Due to C.o.G. of bike+rider system being higher than this force, weight-transfer towards front due to deceleration causes weight-transfer to front and tipping up of bike around front contact-patch.

The higher the deceleration-force (Bf), the higher the weight-transfer. Maximum amount of braking-force is when 100% of weight is on front-tyre. This is when front-tyre has highest friction f=mu. Similar to wings on F1 cars pressing more on tyres to increase traction. If Bf was lower to put rear-wheel back on ground, deceleration would be less.

Reducing braking-force in this case would have him miss turn and go off-road. Note no back brake used at all.

Even 12-yr old girl can do it!

The solution is improved braking-technique through lots of practice.
