When there is no room to start with both wheels on the ground.
1° Balancing on the back wheel (brakes on), lower the front wheel to gain some impulse and torque for the pedal kick.
2° Give a strong pedal kick while pulling a full extension upwards, both legs and arms extended, moving up with the front wheel.
3° Then pull up the bike with you by folding the arms and knees. Apply full brakes as soon as the rear wheel touches the edge.
Starting already in balance on the rear wheel can give you more power for the pedal kick, especially if you amplify the
bouncing effect of low pressure tyres by crouching down rapidly before the pedal kick. If landing only on the rear wheel,
either make sure that you have very good balance, or that you will have some kind of support for the front wheel, onto another
edge. Else try to land both wheels at the same time to ensure a good grip.
Note that landing the front wheel first will give
you extra support to lift further the rear wheel. At the beginning, it is easier to climb with a slight angle, instead of parallel to the step. Start learning on a street
kerb, and then on just everything. Stairways are excellent and the safest way to practice this technique. Also you can make
it more difficult by climbing one step after the other on the rear wheel, without resting the front wheel.
Also try this technique on your bad side (with your good pedal on the side of the step to climb). It is easier than you think, and you will learn more easily how to land the front wheel first for smooth climbing. On your wrong side, you can use the front wheel to grab an edge, even if the rear wheel doesn't reach the final height, and hook the edge with the bash plate or crank protection.
Pushing the move further
Most experienced riders use the front wheel as a guide for the whole bike to land on narrow of very precise areas. Also, using the front wheel helps secure the landing and adds extra support to further lift the rear wheel, allowing to pivot and position the bike even before the rear wheel gets onto the obstacle, for a better control of the alignment.
