Soft Tread Wheels – such as Solid Rubber Wheels, Pneumatic Rubber Wheels, High Temperature Rubber Wheels and Polyurethane Wheels. Soft Tread Wheels are generally kinder to the floor surfaces, make less noise and some are even non marking rubber wheels. Polyurethane wheels tend to sit in-between the two types of wheels, as they have a hard nylon, cast iron or aluminium centre with a softer polyurethane tyre bonded on. This makes the polyurethane wheels some of the most versatile wheels in the range.

Ball Journal Bearings & Tapered Roller Bearings – precision bearings, for heavier load applications Designed for straightforward installation and replacement, making it accessible to a wide range of electric scooter users. The bent valve design offers convenient access for inflating and maintaining the proper tire pressure. Swivel Radius - The distance from the centre of the castor head fitting to the outside of the wheel. This measurement enables you to ensure you have enough clearance for the complete castor to rotate, without being fouled. It is important to take this into consideration when deciding where to attach the castor. Please note braked castors have slightly larger swivel radiuses, as a result of the foot brake mechanisms. The inner tube is resistant to various weather conditions and temperature changes, ensuring consistent performance in different environments.Wheel Type – Wheels can be simply categorised into 2 types, soft tread wheels and hard tread wheels. The general principle is hard tread wheels on softer floor surfaces, and soft tread wheels on harder floor surfaces. This principle reduces the rolling tractive resistance and makes the wheels easier to move.

Roller Bearings – A bearing collar containing needle roller bearings, often the most common and well used bearings. Most suitable for medium duty applications, making the wheel easier to move. We take any issue seriously and consistently resolve any matter fully, swiftly and to your utmost satisfaction. The inner tube is constructed from high-grade butyl rubber or latex, known for its durability, resistance to punctures, and ability to maintain consistent air pressure. What is the overall diameter of the wheel? (From outside edge to outside edge) Diameter of the Hub BoreWe always have one eye on tomorrow. If there is a better metaphorical mousetrap out there, we aim to seek it out. This could be something as simple as a t-shirt or something as revolutionary as a flying car (true to say you are more likely to see a really cool t-shirt here than an eclectic flying car but here’s hoping)! Wheel Load Capacity – all of our wheels have been tested and are able to carry the specified load capacities. Look for thesymbol. Weight bearing abilities can be affected by floor surfaces and amount of use overtime. Overloading wheels will cause them to fail! High Temperature Wheels – we offer a range of hard tread phenolic resin temperature resistant wheels along with a soft tread high temperature rubber wheels. Engineered to be hard-wearing, with a focus on long-lasting durability, reducing the need for frequent inner tube replacements.

At the centre of it all, we are a group of micro mobility enthusiasts who have been riding electric scooters, EUC, e-bikes and eSK8s for many years. In short, we know what works and we only sell what we personally would use. We literally put the personal in Personal Electric Transport. We are always on the lookout for products that are ideally suited for use with the equipment we sell. This runs through all our EUC, e-bike, electric scooter and e-skate accessories and especially applies to our branded products. Health & Safety - All our castors are designed for low speed applications, and power towing castors are available upon special request. It is important to select the right castor for the job, to protect against manual handling injuries.

PET is a community and we always appreciate any ideas for products and design coming from our friends out there. If you think of something exciting that you believe is worthy of our support, make sure you come and talk to us about it! If you are a manufacturer or designer and you are looking for a partner then come and talk to us. Ultimately, we want to create a range of products and micro-mobility, electric scooter accessories that change the way we all think about transportation. Bearings - Choosing castors and wheels with bearings, makes them easier to move, however in certain outdoor and offshore environments standard bearings may cease. Call us for information on stainless steel bearings.

Specifically designed to fit tires with a 200×50 configuration, ensuring compatibility with a range of electric scooters. Tread Width – is the width of the wheel that touches the floor surface. Different types of wheel have differing tread widths. Wide tread wheels are ideal for outdoor environments.

How to Measure Wheels

We offer a range of imperial and metric sizes of tube fittings, so if you are unsure of your size, measure as best you can and we will offer you the nearest options for you. Top tip! Dividing your total load by 3 allows for a margin of safety, and this will give you the maximum each castor can carry in a safe working environment, allowing for uneven floor surfaces. 7 . Other Considerations that may affect your choice? We can offer you wheelbarrow wheels and trolley wheels with or without bearings, with plastic wheel centres or metal, and even a range of puncture proof wheels to suit your requirements.
