Magic Pie

The offer

What Magic Pie actually is

Magic Pie is one configuration from Golden Motor, made in China, filed here as a rear hub. The family is Magic Pie, generation Catalogue. Direct-drive hub with the controller often inside the motor. A long-running cargo and touring kit, front or rear.

In the box, as this record has it: Magic Pie motor, Throttle. Still required before the bike moves under its own assist: Battery, Dropout width, Torque plates. A cheaper advert for the same family name is not this list. If the battery, the charger or the throttle differs, it is a different configuration and it gets a different page.

Off-street in the EU and UK. Used worldwide on cargo bikes and trikes where local law allows.

The price on the card is the maker’s published figure in USD, or Maker list when no figure was published. Allowances for a missing pack, a charger and workshop time sit in the complete-cost band. They are not a second product and they are not a promise that a random pack will talk to this controller.

The bicycle

The frame this motor is asking for

Golden Motor lists Magic Pie against Cargo, Tricycle, Hybrid bicycles, for Load carrying, Touring, Hills. Wheel sizes on the card: 26, 20. The mechanical interface is 135 mm quick release. Brakes are disc.

A rear hub has to share the dropouts with the gears and the brake. 135 mm quick release is not 142 mm thru-axle, and an adapter is a different configuration. The derailleur hanger, the rotor and the torque arm all want the same few centimetres. Internal-gear hubs are a separate build, not a checkbox on a cassette wheel.

Pedals stay. This configuration is a bicycle with assistance, not a motorcycle conversion. Sensor on the card: cadence. Cut-off on the card: not stated. Throttle: fitted on this configuration.

The numbers

1000 W is not the whole story

Continuous rated power for Magic Pie is 1000 W. Claimed peak is not stated separately from the continuous rating. Torque is not published as a crank or hub figure. Manufacturer stated. Motor mass is not published. System mass, once the named parts are on the bike, is Magic Pie motor, Throttle.

Peak is a short claim. Street rules, including the Great Britain check on this site, use continuous rated power and the speed at which assistance stops. A controller that can be unlocked does not change the record of the motor as sold. Magic Pie is filed in the Off-road class: Above street classes. Private land and closed courses.

Off-road on this site means the published rating sits above the ordinary street classes. It is for private land and closed courses unless a specific controller is sold as a limited street version. That limited version would be its own page.

Pack and charger

The motor is not a finished electrical system

Magic Pie is sold as a motor. Voltage class is 48 V. Energy in this offer: no watt-hour figure in this offer. No battery model is invented to fill the gap. The complete-cost band holds an allowance so a finished bike can be budgeted without pretending a pack was included.

The charger follows the pack, not the motor slogan. Budget the charger once the pack model is fixed. Similar voltage, a connector that happens to fit, or the word universal is not a match. The controller in Included controller expects the pack the manual names.

If you already own a pack, the workshop question is the continuous discharge rate, the connector pinout and whether the battery management system will talk to this controller. Those three are not on a watt sticker.

Rear hub

How Golden Motor uses this layout

Rear hub. Magic Pie replaces the rear wheel. Gears, if they are a derailleur, stay on a cassette the hub was built around. The motor’s reaction tries to spin the axle in the dropout every time it drives, which is what the torque arm is for.

Geared hubs are smaller and freewheel when the motor is off. Direct-drive hubs are heavier, can regenerate on some controllers, and drag a little when you pedal past the assist. The card says which one this is only as far as the maker published it. A missing word is not filled in from a similar wheel.

Cable and hose length matter more than people expect. A wider axle, a torque arm and a bigger rotor can use the last centimetre of a brake hose that used to be fine.

The workshop

A workshop path, written as a sequence

Magic Pie is a workshop install in this record. Doing it yourself does not rewrite the path into a pass. It means the documented route was not the one you took, and the result stays conditional until someone competent has seen the bike.

Warranty as published: Maker warranty. Term is on the invoice.. Labour in the cost band is separate from the offer. A brake service the bike already needed, a new chain, or a hanger alignment is not folded into Golden Motor’s price to make the total look neat.

The sensible order is measure, then mount, then connect, then the first assisted roll in the stand. Connectors are keyed for a reason. The torque arm, the axle nuts and the connector boots are one inspection at the end, not three trips.

After it is on

The first month, and the parts that wear

Spoke tension on a motor wheel is part of the service, especially in the first few hundred kilometres while the wheel beds in. A ticking torque arm is a loose bolt, not a personality. Check axle nuts after the first week.

Keep the named charger with the pack you actually fitted. Store the pack cool, part-charged if it will sit, and not in a hallway that is your only exit. Golden Motor’s display, if one is included, is paired to this controller generation. A screen from the next family is not a spare.

My Garage on this device can hold the configuration, who fitted it, and what was still open. That note is for you and for the next workshop. It is not a certificate. If a later notice lands on this configuration, the record is where it should show.

From the library

• What a conversion kit actually includesA motor wheel and a complete system are not the same product. The page should say which one you are looking at.
• Watts, torque, and the sticker that does not mean rangeContinuous watts, peak watts and newton-metres describe different moments. Mixing them is how a listing looks twice as strong as the motor you will live with.
• Speed classes, from 25 km/h to off-roadThe class is a property of the kit as sold. The road you may use it on is a property of the country, and sometimes of the state or the canton.
• Torque arms, dropouts and why the skewer is not the planA hub motor tries to rotate its axle in the frame. The torque arm is how that force goes into steel instead of into a nut.
• Wheel sizes, and why 700c is not a moodThe motor wheel is built for a diameter and a brake. The tyre you like does not retcon the rim.
• Cargo bikes and longtailsThe motor is the easy part. The chain, the brakes and the length of the frame are the job.
