Founded in 2008 by Arnold du Toit, the British design engineer, Drive Daddy Limited has designed, developed and patented a number of innovative technologies for use in a light-weight, battery powered multi-mode personal transportation.
The most developed of these, developed in-house, is targeted at the golf market and branded RolleyGolf.
Other sectors where Drive Daddy Limited's innovative technologies are being developed or licensed include inter alia logistics/distribution, city transportation, media/film and marine.
Get in touch
We at Drive Daddy know that finding the right solution can be a difficult journey. That’s why we offer workshops to walk you through your needs, the scope of your goals, and your budget.
Drive Daddy is currently working on the development of a personal electric vehicle that is hoping to address the problems faced by inner city congestion and pollution.
The golf sector was the initial inspiration for the development of the technologies developed and owned by Drive Daddy Limited. Today RolleyGolf is not only a multiple award winning innovation, it is a proud British made brand. Each of the products are checked by our master-craftsmen, who have over 45 years of engineering experience, hand-building and assembling the collections in the heart of London.
Design is being undertaken to produce an electric ride on delivery vehicle. The vehicle is being developed with only limited modifications to the existing transformable chassis design whereby the ride on vehicle would have the capability of carrying up to eight standard size distribution crates/totes. The offering is cost effective and targeted at the likes of the Royal Mail, Amazon, Yodel, Ocado or other delivery/distribution companies. Key marketing benefits include a reduction in CO2 pollution + other environmental benefits, less congestion in the neighborhoods being delivered to, as well as a smaller storage space requirement (because the vehicle can be folded down) when it is not in use.
Future City Transportation
Early concept stage - Given the functionality and versatility of the product which Drive Daddy has developed for the golf market, There is potential to exploit the Business’s IP and develop a Lightweight Individual Multipurpose Electric Vehicle (LIMEV) which complies with the regulatory requirements set out in Future City Transport, which individuals could use as an alternative to say a Boris Bike, public transport or walking.
The Business is licensing the TWINDRIVE technology to ASAP Watercrafts, a UK based business which is developing an electric power assisted water craft for beach lifeguards as a cheaper alternative to a jet ski.
Security and Defense
Our technology has been applied to help move soldiers and security around their area of deployment, quickly and safely.
Drive Daddy is currently prototyping a first response shelter to be used by search teams after natural disasters, the shelter is fold-able, easily transportable and keeps the occupants off the ground and away from contaminated water
An internal project to help give more freedom to wheelchair users by creating a lightweight off-road wheelchair that can negotiate any terrain but does not need a van or trailer for transport.
TWINDRIVE effectively powers an electric-control-system (“ECS”) and dual AC induction motor.
Regenerative braking is also controlled by TWINDRIVE - which means that as soon as the wheels are turning, the regenerative braking system is readied for operation.
This technology is unique in that it has been developed so that:
a) The motors are in constant drive, thereby enabling the product to use the power both simultaneously and independently; for example: on a steep hill or slippery terrain when one motor needs to produce suitable power to enable the product to move in a controlled manner with the added benefit of ensuring minimal damage to the ground underneath; and
b) The regenerative braking software is linked to the acceleration/deceleration profile (similar to what you might find in Formula 1 KERS technology). It is extremely effective, especially on the downhill, where the constant drive brings the vehicle to a controlled stop without compromising the safety of the user. The braking also has energy harvesting capabilities to optimize battery range.
While the technology, as is currently formed, can control two motors. The controller unit has the potential to be expanded so that it controls up to eight independent electric motors.
Within the design specification, the chassis is able to seamlessly transition into a multitude of different modes depending on the product.
Every chassis we create we aim to achieve the following:
a) Strong: Designed to be sufficiently robust to carry an above average weight rider, complete with associated baggage;
b) Lightweight: Light enough for a single person to fold and lift into a car (i.e. less than typical airline luggage threshold of 23 Kgs)
c) Transformable: Ability to ride on or walk with, or fold up for easy transportation.
Weight to strength ratio is fundamental to ensure the product is robust enough to take all weights of the rider and their equipment across all sorts of terrain, but also be lifted into the back of a family car.
