You know the feeling: the route would still be so beautiful, the trail goes on, but the battery says no. Suddenly, everything revolves around the question of where the nearest power outlet is – and no longer about where you actually want to go.

This is exactly what needs to stop. The SolarRide Explorer Bundle makes your e-bike independent of the power grid – with 162 watts of solar power, a smart 3-in-1 charger, and a packing size that fits into any saddlebag.

Why range anxiety is not a law of nature

Anyone who goes on multi-day e-bike tours knows the mental calculation: How many kilometers can the battery manage? Is the campsite close enough to a power outlet? Is there enough energy for the detour to the viewpoint?

This calculation is based on a single premise: that your battery will only go as far as you charged it beforehand. The Explorer Bundle breaks this logic. As long as the sun shines – or a 12V source is nearby – energy is continuously supplied. You plan again according to the landscape, not the charge level.

What's in the Explorer Bundle

The bundle combines two components into a complete system:

SunLight – the 3-in-1 charger

The SunLight is the heart of the system. It sits between the energy source and your e-bike battery and takes over the complete charge control: fully automatic, without settings, plug & play.

What makes it special: It supports three completely different energy sources via the same output:

Solar via folding module – the charger processes input voltages from 10.5 to 30 volts and uses MPP tracking to get the maximum yield from the solar panel at all times. With 95% efficiency, hardly anything is lost.

12V cigarette lighter – whether in the car on the way to the trail, in the camper, or on the onboard battery: the SunLight also charges via any 12V vehicle source. Integrated software protects the vehicle battery from deep discharge – you can continue driving without problems after your battery has been charged.

Power outlet – the included power supply unit from GreenCell enables classic charging at home or at any campsite connection, with full charging power of 3.3 A.

The housing is made of aluminum, water-resistant according to IP 65, and weighs just 350 grams. All currents, voltages, and temperatures are monitored in real-time. Towards the end of the charging process, the SunLight automatically reduces the charging power – this protects the battery cells and extends their lifespan.

162W Ective folding module

The solar module is the second component of the system and solves the classic problem of portable solar energy: either too large for on the go or too weak to really make a difference.

162 watts of monocrystalline power with 23% cell efficiency provide approximately 20% charge per hour for a 500 Wh battery under good conditions. Unfolded, the module measures 1185 × 866 mm; folded, it fits into a DIN A4 case with a depth of 11 cm. Weight: 4.3 kg.

The case also includes two hook straps that allow you to easily hang the module on the parked e-bike. This way, it is optimally aligned with the sun, and the battery and charger remain in the shade. Integrated USB ports allow you to charge your smartphone or other devices simultaneously.

In practice: This is what a tour looks like with it

You start in the morning with a full battery. At noon, during a stop at the mountain lake, you unfold the module, hang it on the bike, and leave it in the sun for an hour. When you saddle up again, 20% has been recharged. For a 500 Wh battery, this is 100 watt-hours – enough for another 30 to 40 kilometers depending on the terrain.

In the evening at the campsite, the camper's auxiliary battery or the car's cigarette lighter is running. The SunLight takes over, and you take care of dinner.

The entire system fits into the saddlebag. The additional weight of about 5 kg is barely noticeable in terms of consumption – and, measured against the independence gained, is no longer an argument.

Compatibility: Which e-bikes does it work for?

The Explorer Bundle is compatible with a variety of e-bike brands and battery systems. When purchasing, simply select the appropriate adapter cable for your system:

• Bosch eBike System 2 (2013–2023)
• Specialized 36V
• Yamaha Intube 500 Wh and frame battery
• Brose 36V (Rosenberger)
• GIANT (6-pin and XLR-3)
• FAZUA 36V / 250 Wh
• BIONX 36V, Samsung SDI 36V, Stromer 36V
• Coboc (Rosenberger), XION / Impulse Evo / Green Mover
• Anderson Powerpole, Hollow plug 5521

What distinguishes the Explorer Bundle from a second battery

A spare battery costs between 500 and 900 euros, weighs 2.5 to 3 kilograms, and must be charged beforehand. It gives you more range once – once empty, it's empty.

The Explorer Bundle costs 599.99 euros, weighs 5 kg in the case, and provides energy as long as there is sun or a 12V source. It is not a one-time buffer, but an open system without a fixed range limit.

Conclusion: The complete system for true touring freedom

The SolarRide Explorer Bundle is not an accessory that you pack as a safety net and never need. It is a complete charging system that fundamentally changes multi-day tours, bikepacking, and camper trips.

No range planning around power outlets. No heavy additional battery. No restrictions on route choice.

Instead: a DIN A4 case in the saddlebag, 162 watts of solar power, and the freedom to go where no e-bike has gone before.
