Eureka

Eureka Electric Tricycle

The Eureka is a compact electric tricycle designed to combine easy access, load-carrying capacity and particularly agile handling thanks to its main distinguishing feature: a tilting system that allows the tricycle to lean while riding.

Its open, low-step frame makes getting on and off the tricycle easier, while its compact dimensions, with just 64 cm between the rear wheels, make it easy to manoeuvre in confined spaces, pass through most doorways and travel along narrow routes where a larger conventional tricycle may be less practical.

In addition to everyday journeys, the Eureka can be particularly useful for companies, industrial facilities, warehouses, private premises or users who need to make frequent trips while carrying loads. Its front and rear baskets, included as standard, provide practical carrying capacity while maintaining a compact and functional configuration.

Tilting system: what makes the Eureka different

One of the features that most clearly sets the Eureka apart from a conventional tricycle is its tilting system. A control located on the handlebar allows the tilting mechanism to be locked or unlocked, completely changing the way the tricycle behaves.

With the system unlocked, the Eureka can lean sideways when cornering, providing a more dynamic and natural riding experience than a rigid tricycle. The rider can move with the tricycle through the turn in a way that feels closer to riding a bicycle.

This design helps reduce one of the characteristic sensations of rigid tricycles: the tendency for the rider's body to move towards the outside of a turn. By allowing the tricycle to lean, the Eureka offers a different and particularly agile way of negotiating corners.

Important: a tilting tricycle requires balance

Precisely because the Eureka can lean, it is important to understand that it does not behave in the same way as a rigid tricycle. When the tilting system is unlocked while riding, the rider must maintain and control their balance in a similar way to riding a bicycle.

For this reason, if you are primarily looking for a tricycle because you have difficulty maintaining your balance on a bicycle, the Eureka's tilting system may not be the most suitable option. In this case, we recommend considering one of our rigid tricycles, such as the Swish, whose handling characteristics may be better suited to this type of need.

The system can be locked and unlocked using the control located on the handlebar, allowing the mechanism to be stabilised when necessary. Understanding this difference before choosing is essential to determine whether the Eureka is really suited to the type of riding you are looking for.

250 W or 500 W Bafang front motor

The Eureka is equipped with a Bafang motor integrated into the front wheel, available in 250 W and 500 W versions. Its cadence sensor detects pedalling and activates the assistance corresponding to the selected level, allowing the rider to receive substantial assistance without having to apply significant pressure to the pedals.

The 250 W version is intended to retain the characteristics of an electrically assisted bicycle, provided that the limits and requirements established by the applicable regulations are respected.

For use in private premises, industrial facilities, private estates or other areas where road traffic legislation applicable to public roads does not apply, the 500 W configuration provides greater assistance, which can be particularly useful when carrying loads or tackling gradients. This 500 W motor version does not meet the requirements of an EPAC for use as a conventional bicycle on public roads and must therefore be used in accordance with the applicable regulations.

Throttle and pedal assistance

The Eureka can be equipped with a throttle, allowing the motor to be activated without pedalling. This can be particularly convenient for certain types of private use, when setting off or when we want to move the tricycle with minimal physical effort.

Regarding its use on public roads, a throttle capable of propelling the tricycle without pedalling is in a similar regulatory situation to the 500 W motor configuration: its use does not correspond to the operation of a conventional EPAC and must comply with the regulations applicable in the place of use.

Shimano Nexus: 3- or 8-speed internal gearing

The Eureka can be configured with a 3- or 8-speed Shimano Nexus system. Unlike a conventional derailleur drivetrain, the Nexus system houses its mechanism inside the hub, providing a particularly practical transmission for a tricycle intended for both everyday use and carrying loads.

The different gear ratios allow the rider to adapt their pedalling to the terrain and the weight being transported, using easier gears when tackling climbs and higher gears when travelling on more favourable surfaces.

Four battery capacities up to 930 Wh

The 36 V electrical system can be combined with different battery capacities, allowing the Eureka to be adapted to the type of use and the usual distance of your journeys.

Currently available options include 370 Wh (36 V / 10 Ah), 560 Wh (36 V / 15 Ah), 745 Wh (36 V / 20 Ah) and 930 Wh (36 V / 25 Ah) batteries. This allows you to choose anything from a more compact capacity for shorter journeys to a high-capacity battery for users who need to travel longer distances or want to reduce charging frequency.

As a reference, in our own tests with the 10 Ah battery, the smallest capacity available, we covered approximately 40 km while riding mainly on flat terrain, with a rider weighing around 70 kg, correctly inflated tyres and allowing the electrical system to provide practically all the assistance possible. Under similar conditions, but with the rider contributing more through pedalling, we were able to reach approximately 70 km.

These figures should be regarded as a reference based on our own tests and not as guaranteed range figures. Actual energy consumption can vary considerably depending on the assistance level, motor power, total weight being carried, tyre pressure, elevation changes, type of terrain, temperature and, especially, the amount of effort contributed by the rider.

KD21C display with Walking Mode

The KD21C LCD display, located on the handlebar, provides easy access to the main riding information and controls for the electrical system.

Assistance can be configured with 3, 5 or 9 levels, allowing the rider to choose between a simpler setup with fewer steps or more progressive control of the assistance provided by the motor.

The display also provides access to different system configuration parameters. Any modification of the original parameters that could alter the legal classification of the tricycle must be made under the user's responsibility and in accordance with the regulations applicable in the place of use.

It also features Walking Mode, which allows the motor to move the tricycle at a speed of up to approximately 6 km/h while you walk alongside it. This is particularly useful on a three-wheeled vehicle when it needs to be moved on foot, especially when carrying a load or negotiating a ramp.

Brakes adapted to its three-wheel configuration

The braking system combines a Tektro V-Brake on the front wheel with a Shimano drum brake on the rear axle, providing progressive braking and control during everyday journeys.

This configuration acts on both the front wheel and the rear axle assembly, adapting to the particular characteristics of a tricycle and to the weight distribution that occurs when carrying loads.

20" wheels: compact and manoeuvrable

The 20-inch wheels help keep the Eureka compact and its centre of gravity relatively low, two particularly useful characteristics for a tricycle designed to manoeuvre in confined spaces.

The Eureka uses Kenda tyres up to 2.125" wide and can be configured with different tyre styles and tread patterns, including road, mixed-use or whitewall options, depending on configuration and availability.

Two baskets included for carrying loads

The Eureka comes as standard with a front basket and a large rear basket, providing space for shopping, personal belongings, tools or other loads without the need to install additional accessories.

The maximum permitted load is 150 kg, taking into account the total weight of the complete assembly: tricycle, rider and transported load. It is important to respect this limit and distribute the weight correctly to maintain appropriate handling while riding.

A comfortable and adaptable riding position

The adjustable saddle and handlebar heights allow the riding position to be adapted to users of different heights. Its design encourages a relatively upright posture, particularly suitable for relaxed journeys and for riders who prioritise comfort and ease of use over a sporty riding position.

Thanks to its open frame and low step-over height, getting on and off the Eureka is also easier than on a conventional bicycle with a high top tube.

A tricycle for personal and professional use

The combination of compact dimensions, two baskets, electric assistance and a maximum total load of 150 kg allows the Eureka to be used in very different situations. It can accompany you on everyday journeys, shopping trips or leisure rides, but it can also become a practical tool for warehouses, factories, private premises, facilities or businesses where numerous short journeys need to be made while carrying materials.

For this latter type of use, particularly when operating exclusively in private areas where legislation applicable to public roads does not apply, choosing the 500 W motor can provide additional assistance when moving the tricycle with a load.

Experience, warranty and after-sales service

At Bikelec, we have been working with electric mobility since 2007. This experience is particularly important with products such as electric tricycles, where not only the electrical system but also the mechanics and handling characteristics differ from those of a conventional bicycle.

The Eureka comes with a three-year warranty on all its components. In addition, our after-sales service remains available after delivery to answer questions, diagnose possible issues and supply any necessary components or spare parts.

Who is the Eureka electric tricycle for?

The Eureka is particularly suitable for users looking for a compact tricycle with good carrying capacity and more dynamic handling than a rigid tricycle. Its tilting system allows the rider to lean into corners in a way that is closer to riding a bicycle, while its two baskets and different battery and motor options allow it to be adapted for both personal journeys and certain professional applications.

However, choosing between a tilting tricycle and a rigid tricycle is fundamental. If you know how to ride a bicycle and want the practical advantages of three wheels without giving up dynamic handling, the Eureka offers a very distinctive concept. If your main priority when choosing a tricycle is not having to maintain your balance while riding, we recommend considering a rigid tricycle such as the Swish.

If you are unsure which of the two systems is better suited to your needs, our team can advise you before you make your choice. With a tricycle, choosing the right type of handling is just as important as selecting the motor or battery capacity.
