• Standing alongside the tricycle, hold the brakes, and apply the parking lock to stop the tricycle from moving.
• Posion yourself holding onto the handlebars so that you can place a leg over/through the tricycle frame unl you are
standing evenly over the tricycle frame with a foot on each side. Don’t try to swing your leg over the back basket area,
it is not safe to do so.
• Using your strongest leg, place your foot onto the pedal, when the pedal is at the lowest posion, then stand on the
pedal to li yourself and up and get your body posioned onto the seat correctly. If you can get onto the seat from
ground level without standing on the pedal then the seat is set too low for you. Connue with both feet on the pedals
at all mes.
• Once comfortable, release the parking lock and either pedal the trike without electric assistance or, if choosing electric
assistance, go through the electrical start-up details below.
• Turn the Sobowo electric tricycle on by turning on the handlebar controller. The colour LCD display will light up. Select
the desired starng speed. The speed range 1-5. 1 is the slowest seng with 5 being the fastest.
• Decide if you want to operate as pedal assist or with twist throle.
• Pedal assist mode, start to pedal and electric assistance will engage aer half-to-one turn of the pedals.
• Throle mode, press the red buon to turn the throle on and twist the throle for the desired speed level.
• With both feet on the pedals at even level, push o with your strongest leg, looking ahead for pavement condions/
obstacles and for other road users/trac.

Riding continued
• If riding in pedal assist mode, power will engage aer half-to-one turn of the pedals. In throle mode at the same me
as pushing o, twist the throle slightly using your right hand to introduce electric assistance .
• You will not lose your balance on the electric tricycle so always keep both feet on the pedals at all mes.
• Ride and control the tricycle up to your desired speed. Don’t ride too fast unl you are fully familiarised with the
Sobowo electric tricycle, its performance, stoping distance and handling characteriscs.
• Slowly squeeze the brakes to get the feel of how they work and their strength.
• The brakes on your Sobowo electric tricycle are high-performance, hydraulic disk brakes, and they will reduce your
speed very quickly. About 70% of the braking power will come from the front wheel, but use front and rear brakes
together for the best stopping performance.
• The brake lever on the le-hand handlebar operates the two rear wheels, and they brake/stop together. The brake
lever on the right-hand handlebar operates the front wheel.
• When pushing/walking the tricycle manually, please turn o the power at the key to avoid accidental acceleraon and
