Bearings manufacturer Vesconite’s self-lubricating, wear-resistant bushings have been selected for e-bike developer Tadhole’s new line of three- and four-wheel electric vehicles.

Initially developed as golf cart alternatives, the lightweight vehicles have attracted growing attention from recreational users, security personnel, retirees in gated communities and eco-tourism operators.

“The design philosophy was to develop a low-cost, lightweight, low-maintenance cart with extreme comfort, ease of handling and a high fun factor,” says Tadhole co-founder Barend Botha Snr.

This philosophy led to Tadhole’s choosing the Vesconite bushings for critical suspension and steering pivot points.

“Vesconite’s mechanical strength, self-lubricating properties and long wear life without maintenance make it the ideal choice,” says Botha.

After 15 000 km of use on a battery-powered electric tricycle, Vesconite suspension and steering bushings show no signs of wear and have run entirely without lubrication, Botha reported.

The bushings help reduce the need for ongoing servicing, especially in hard-to-reach suspension areas that traditionally require grease or replacement.

“Using Vesconite supports our concept and enhances the driving experience. Our prototype was close to the current design, with only minor changes over time, which shows we got the engineering approach right from the start,” notes Botha.

The concept’s origin was conceived in 2018, when Botha and his son designed a reverse trike pushcart using bicycle parts. The unique layout was chosen to improve the pusher’s ability to run at speed, but also proved ideal for stability and control, laying the groundwork for the single-seater electric cart. A South African and US patent have since been granted for the design.

The flagship three-wheeler and the newer tandem four-wheeler both use modular construction, making them easy to adapt for different applications. Bicycle parts and e-bike motors further support the project’s goals of low cost and low complexity.

Ten pre-production units were initially built and tested extensively, followed by several pre-ordered carts.

Versatility

Weighing 45 kg for the single- seater and 75 kg for the four-wheeler, the vehicles are highly manoeuvrable and easy to transport.

The “quiet, nimble vehicles” also appeal to older users and those with mobility challenges. To improve access for mobility impaired users, Tadhole has developed a swappable front nose, facilitating recreational use on trails, in game reserves and on beaches.

For added versatility, the four-wheel version includes a removable rear seat that can be swapped for a small cargo bin. Optional accessories make it a strong candidate for the eco-tourism sector.

Tadhole reports increasing interest and orders for all models. While still assembling to order, the company is increasing capacity to reduce lead times as demand grows, with agents in Gauteng and the Western Cape and soon in KwaZulu-Natal.

The feedback has been “overwhelmingly positive”, says Botha.

Tadhole is based in South Africa, but the company is looking to expand to the US market. Early exports include two vehicles shipped to Texas, where a US-based partner is showcasing the product and seeking investment to establish a manufacturing facility.

“We believe this product can bring joy and practical benefits across age groups and industries. With Vesconite bushings reducing maintenance and increasing durability, we are confident in its long-term performance and appeal,” Botha concludes.
