Preferably, as shown in figure 5, the trailing wheel shown in Fig. 4 is provided with braking mechanism 50, the braking mechanism 50 includes：Dish
Brake device, the disc brake are provided with disc 52；The wheel disc 613 is engaged with the disc 52, in rear wheel, disc 52
It can be rotated with trailing wheel 26, now disc brake is in open configuration；When disc brake is in clamped condition, disc 52 clamps trailing wheel
Frictional force is produced, may be such that wheel stops operating.Preferably, the braking mechanism 50 can be coupled with the handle assembly 20 and constructed
For hand-operated breaking mechanism.
In another preferred embodiment, the personal mobility vehicle also includes the second motor, and second motor can
At least one trailing wheel at least two trailing wheel is operatively coupled to provide revolving force at least one trailing wheel.It is excellent
Selection of land, the controller are configured to allow user to control transmission of the revolving force at least one trailing wheel so that described
Trailing wheel is rotated with friction speed around the main shaft.The controller controls two trailing wheels to produce speed difference and may be such that tricycle is complete
Acted into drift.
However, other multi-direction wheels usefully instead of trailing wheel 26 and can will can reach the purpose of the present invention.For example, can
To be replaced with the Transwheel TM of the comprehensive wheels of Airtrax TM (Chicago) or Kornylak Corporation.
In a preferred embodiment, the first motor 30 is installed on tricycle 10, for example, be installed on framework 12 or
Person is preferably mounted on front fork 13 so that when user starts to start front-wheel 11, the first motor can be by front fork 13 around steering
Axle rotates.Preferably, the surface that steering spindle is supported on or ridden over relative to tricycle 10 tilts.Preferably, turn to
Axle is rearward inclined upwardly certain line, and this line extends perpendicular to the surface that tricycle 10 is supported on.First motor
30 are preferably mounted in the top of front-wheel 11, and are operably coupled to front-wheel 11 so that electronic rotation power is electronic from first
Machine 30 is delivered to front-wheel 11.In another embodiment, the first motor is supported on wheel by front fork 13 or by wheel shaft or wheel hub
Near hub.Or first motor 30 one can be formed with front-wheel 11, and can be configured to directly drive front-wheel 11,
It can be wheel hub motor.In other embodiments, the first motor 30 can include being operably coupled to front-wheel 11 for no reason
Transmission system, and the transmission system for no reason can include for rotary power being delivered to the chain or belt of front-wheel 11.Again
In some other embodiments, the vehicle includes the transmission device being operably disposed between the first motor and front-wheel 11,
And the transmission device drives the axle of front-wheel 11 or hub from the first motor passing power.The transmission device can be tooth
Wheel-type transmission device and clutch or freewheel can be included, this allows front-wheel 11 being not affected by the driving of the first motor
When rotate.
Arrestment mechanism includes the second brake bar 40 and brake disc (Fig. 8).Second brake bar 40 is operably mounted at handle
It can be got on component 20 and preferably while the direction controlling to tricycle is kept by user.In operation, actuating the
Two brake bars 40 can cause the second brake bar cable to be tightened up and be moved up towards handle assembly 20, relative so as to activate a pair
Clamp and make the clamp that friction brake force is applied on the side of brake disc.In a further advantageous embodiment, can be with
Frictional force brakes power is applied on the wheel rim of front-wheel 11 using traditional bicycle clamp or cantilevered brakes.At it
In his embodiment, drum brake can be used.The several version of preceding arrestment mechanism is possible, and art
Those of ordinary skill it will be appreciated that present application wishes to cover any such change, use or modification of disclosed device.
In one preferred embodiment, the second brake bar 40 of actuating can cause friction brake force to be applied in brake disc, and can make the
One motor 30 is kept apart with its power supply (for example, battery 48 in Fig. 7), so that once having activated the second brake bar
40, the power transmission from the first motor 30 to front-wheel 11 will be weakened or terminate.Although shown power supply is battery 48,
Other suitable power supplys can also be used.Therefore, unless otherwise directed, otherwise, the use of term " battery " is general in the present invention
It may refer to suitable power source.Arrestment mechanism is operably coupled to the motor 30 of battery 48 and/or first, in order to reduce or stop
Only arrive the power transmission of front-wheel 11.Activating the second brake bar 40 can stop passing from the electric power of the motor of power supply 48 to the first 30
It is defeated, and/or it can stop the power transmission from the first motor 30 to front-wheel 11.A kind of such arrangement with the addition of cut-out
Switch, the roof-cut resistence are activated together with the actuating to the second brake bar 40 or the other parts of brakes.It is another
Kind arrangement can be that clutch is added between the first motor 30 and front-wheel 11, and the clutch is in the second brake bar 40 or system
The other parts of motivation structure activate when activateding.In other embodiments, the second brake bar 40 can alternatively for can by with
The bar or button that the pin at family is got at, such as by riding 22 bars supported.
With reference to figure 6 and Fig. 8, shown driven pulley, driven gear or driven sprocket 34 are installed on the axle or hub of front-wheel 11,
So cause the revolving force being applied on driven sprocket 34 that front-wheel 11 can be driven to rotate.Driven sprocket 34 passes through transmission ring for no reason
The power transmission shaft that (for example, driving belt or shown driving chain 32) is operably coupled to the first motor 30 (preferably supports
Driving wheel, driving gear or drive sprocket).In a preferred embodiment, driving chain 32 is operably coupled to be connected to
Driven sprocket 34 on the axle of front-wheel 11, the driven sprocket 34 include one-way clutch mechanism, the one-way clutch mechanism
It is configured such that front-wheel 11 can be rotated (that is, hypervelocity clutch under relatively large speed compared with driven sprocket 34
Device).In another embodiment, the first motor 30 is configured to drive front-wheel 11, and its mode is using roller or other biographies
Revolving force is applied directly to the outer circumference of front-wheel 11 by motivation structure.Another embodiment includes being located at the first motor 30
With the transmission device between front-wheel 11, the transmission device is configured to drive using power caused by the first motor 30
The axle of front-wheel.For example, the gear type transmission device with clutch can be used for driving front-wheel 11.In an alternate embodiment
In, the first motor 30 can be positioned near the axle of front-wheel 11, and can be integral with the wheel shape, so that the
Revolving force is directly delivered to the wheel and drives the wheel by one motor 30.
Brake disc is arranged on the axle of front-wheel 11 and relative with the driven sprocket 34 on front-wheel 11, so as to braking
Disk, which applies brake force, can cause the slow its rotation of front-wheel 11.Some conventional tricycles include the pedal being couple on front-wheel, with
Just user is allow to promote tricycle forward.It is being seated however, the embodiment of this tricycle includes user and is operating tricycle
The alternative placement of its pin simultaneously.One preferred embodiment further comprises foot-operated 22, and described ride is configured to make user can
