The 24" Alpha Four offers an NEW 9-speed Microshift drive train. The 11-36T wide range gearing is the real deal and gives growing riders truly usable gear range.
Prevelo crank lengths are custom sized for each size bike to make sure little riders have optimum pedal ergonomics. And they have ultra-narrow Q-factors to match the narrow hips of young cyclists. If that sounds like technical mumbo jumbo, here's the point - Prevelo cranks will help make small riders more comfortable and efficient on their bike.
Confidence Inspiring Geometry
The Alpha Four features Prevelo's signature confidence inspiring geometry. Prevelo geometry utilizes a low bottom bracket that lowers the center of gravity of the bike and rider, making for a more agile and confident ride.
9 Speed Microshift Drivetrain with Wide Span Gearing
9-speed Microshift drive train and 11-36T wide range gearing is the real deal and gives growing riders truly usable and class leading, 327% gear range. Kids are going to be efficient on the flats and have the leverage of low gears available to help make it up tough hills.
Kid Optimized Cockpit
This is where little riders command their steed. It's decked out with ultra thin grips and short reach brake levers that are optimized for small hands. The Microshift shifter is operated with two easy to operate thumb levers.

- Prevelo confidence inspiring low and narrow geometry. Prevelo geometry keeps the rider low, balanced and in control.
- Lightweight 6061 aluminium frame with custom formed tubing.
- Lightweight aluminium alloy fork with chromoly steerer.
- Tektro front and rear v-brakes.
- Lightweight Allen head front and rear wheel skewers for secure wheel installation.
- Three piece crank with squared taper bottom cartridge bearing bottom bracket and ultra narrow Q factor.
- Custom made cranks. All Prevelo cranks are sized specifically for each model bike, down to the millimetre.
- NEW Microshift 9-speed drivetrain. Uses a shorter pulley cage without comprising gear ratio width. Because kids’ bikes have small wheel diameters, rear derailleurs on kids bikes hang low and close to the ground. The Prevelo Alpha bikes use smaller cage derailleurs to keep things high and away from the ground.
- Microshift Trigger Shifters. Small hands have a hard time using twist shifters. We use reliable silky smooth thumb shifters. They are easy for small hands to operate, and operate just like shifters on high performance bikes.
- Replaceable derailleur hanger. If the derailleur takes a hard hit, the hanger can be replaced without repair to the frame.
- 11-36T wide span gearing gives riders plenty of range to spin up tough hills.

Ready to ride
Every bike from Start Fitness is fully checked & assembled before despatch and will arrive, almost, ready to ride. Each bike is assembled by one of our CyTech accredited mechanics and then packed into one of our custom boxes.
*This process has a lead time of 2-4 working days.
Unfortunately during peak times this may be slightly delayed. We will however, aim to despatch your bike as quickly as possible. Minimal assembly, with basic tools, is required before you can ride. Assembly tools are not usually included.
Making sure you are home
Once fully checked and boxed, we will contact you to arrange a suitable delivery date when you will be home to take delivery. Our bikes are despatched with a premium delivery service which usually delivers next working day (excludes weekends & bank holidays) for mainland UK orders, it may take slightly longer for some areas, Northern Ireland, Channel Islands and outlying Scottish areas. European bike deliveries usually take approximately one week.
Taking Delivery
Any mechanical or cosmetic issues need to be reported to us within one week of the delivery date. If you do not plan on using the bike straight away, we advise that you remove it from the box and check it over ASAP as we cannot be responsible for any reported issues (other than standard warranty issues) later than one week from the date that the bicycle was delivered.
First Service
After a few weeks of riding (we recommend around 6-8 weeks, regardless of how much the bike has been used), a new bike will need a service to make final adjustments and to re-check all nuts and bolts. This is necessary as the bike goes through a ‘bedding in’ phase, after which, final adjustment may be necessary. We recommend that this is carried out by a CyTech qualified mechanic.
It is important to have these checks carried out to prevent any avoidable problems which may not be covered by warranty and to ensure the smooth running of your bicycle. If you’re local to us, we’re able to offer this first service free of charge* at our Newcastle store (NE1 6JE). You’ll just need to call our workshop on 0191 917 3825 to book your service in, and don’t forget to bring your proof of purchase when you drop the bike off with us.
If you’ve had the bike delivered, it will be your responsibility to ensure a first service is carried out at a trusted bike shop local to you, preferably by a Cytech certified mechanic. Start Fitness are unfortunately not able to cover any costs associated with this service if carried out by another store.
*Please note that this complimentary check-over does not include any labour to replace worn parts or to fit new accessories. All bikes should be delivered to us in a clean and serviceable condition, or a £15 cleaning charge will be payable.
Bike Servicing
Bicycles need to be serviced regularly, as a guideline we would advise on at least one full service per year and/or a standard service twice a year. If the bike is used regularly in adverse conditions, more regular servicing may be required.
