Last week I was doing 30 something kmph ob my bike, I was on the most right hand lane and I wanted to make a u-turn so that meant I had to go through like 5 lanes because the u turn was on the left. My mirror was not properly adjusted so I had to look behind me to the left to switch lanes. I was looking to the left and when I turned my head to look to the front I found my self going straight into a car, so I quickly grabbed the brakes next thing I knew I was flying off the bike and onto the road. I tried to think of what might've caused this, I didn't crash into the car and there was no gravel/sand at all on the road, so I figured I must've grabbed the front brake too quickly. Is this possible? I've been riding for only less than 2 months now (still learnig) and my bike has ordinary brakes (not ABS). This is the third time I've fallen off the bike, the first two times I was braking on sand/gravel so the wheels skid. Luckily I got back up right after I fell and ended up with no injuries at all and no damages on the bike.

You sound like you really need to take some lessons.

From an initial point of view it sounds like your front wheel probably wasn't straight when you harshly applied the front brake, which would throw the bike down to the floor and consequently you off of it.

Yes Thumbs Up

Think about the physics of riding a bike - if you put the front brakes on, energy/weight of the bike transfers to the front wheel. If there is too much energy to be sent forwards in a straight line, it will find another direction to go; upwards. The bike will do the opposite of a wheelie.

Nothing good ever comes out of this...
Front brake's usually quite powerful = easy to lock the front wheel and off you go flying.

It's worrying that you were not taught this on your CBT.


Without sounding horrible, you're a bit of a danger to yourself and other road users. Get some training asap.

Your list of mistakes is long

Mirrors not adjusted
Where you look is where you will go. You were probably swinging left as you looked
You applied front brake without back
You probably had the bike turning as you braked and rear wheel tried to overtake

As a learner what you doing in the right overtaking lane

Advice isn't what you need. It is lessons

Yep, what that guy said....

The first thing I was taught on my cbt when it came to braking was to never snatch at the brakes. I'm quite concerned that you needed to ask on a forum if snatching the front brake could have caused your crash? Being involved in the accident yourself i think you should probably have been able to assess your mistake yourself.

Either way, take it easy, give cars in front a bit more space and be safe man!

Is a CBT compulsory in the UK? Must you do mandatory certified training? Sounds like it should be.

Here it isn't but I would never let anyone ride without it. When my last GF wanted to learn, I told her no way, go to a cerified acadmey and I will pay. The kind of thing above explains why. Taking a tumble in the right lane in traffic is asking to be run over by a cage who can't 'grab' at his brakes fast enough. No cager expects a bike to just go down in front of him.

Reading the american HURT report or the euro MAIDs one is a good start to seeing how accidents happen and how high risk you are. A learner rider in traffic with no course is very high risk.

The compendium of mistakes above is an example why, and suggests the rider needs a bit more time in a parking lot or track to grasp the fundementals before tackling traffic as well and having divided attention

Of course it's possible to crash by braking too hard! Have you never jammed on the front brake on a bicycle?

If this is a troll it's one of the blandest attempts I've seen yet.

I still have scars on my knee and on my elbow from putting the front brake on my push bike far too much when I was a kid and going over the handlebars. Learned that lesson young Thumbs Up

They've all been pretty bland tbh.... but all blatantly obvious. But hey ho, if it gets people talking then maybe its a good thing...it is a forum afterall.

*Awaits next troll thread. Confused

I want to Ride a Motorbike! Tell me more about CBT?

Yup. The 'C' in CBT stands for Compulsary...

Its a Compulsary-Basic-Training course, and UK riders need to have completed the course with an Driving standards Agency acredited school to gain a 'Cirtificate of Completion' or Ministry form DL196, which is valid for two years and 'validates' the learner motorcycle entitlement of their driving licence. You cant go out on the road legally until you have done the course.

Link explains more about it and the test system in the UK.... though all changes on the 19th thanks to the Eurocrats in Brussels.

But 'The Course' is pretty thorough and the DSA have very clearly set course 'sylabus' of both class-room lessons and on bike excersises, and the progression from where the controls are and what they do, up to wobbling around cones on a car-park and thence ultimately onto a public road, is all very well prescribed and standardised. Course is designed to nominally take about eight hours or one day for an 'average' newbie to complete, with four hours hands on in the saddle practice included.

And its fairly well regulated, so that what you get at one school is the same as you ought to get at another; its not left to the instructor to just teach what they think a student needs or anything.
