Radian: The Future of Enduro is coming!

[Tim - Radian]

Hi fellow Electric Dirt Riders!

I’ve been on this forum for a few years now. In the background I have been working together with a passionate team of ex-Electric Superbike Twente members on a big project. I’m really excited to show you guys what we have been working on for these past 4 years. Follow our social media channels to stay in the loop. We will go live tomorrow at 14.00 CEST!

I have been invited to take a look at their bike and it's really legit

That's all i have to say about it until they release it tomorrow!

We're live guys! Hope you like it!

Lots of interesting design choices in there

Radian EXR – Electric Enduro Motorcycle

70 hp electric enduro with 30-second battery swaps. InfiniPack system, 60-115 km range, 1060 Nm torque. Competition-ready from €14,450. Available Q4 2027.

www.rideradian.com

Real swappable batteries (two 22 kg modules of 4.3 kWh each) and charging outside the bike are game changers.
Storage space for onboard charger
Minimalist dash with companion app

For the spec geeks:
intended vehicle weight 125 kg
70 hp
8.6 kWh
production date aimed for Q4 2027
90 min 20-80% charging (3.3 kW charger)
KYB, Brembo...
Street legal in the EU
14 k€

Playing with numbers, battery configuration could be 80S6P with 5.0 Ah 21700 cells (nominal voltage 288 V, 8.6 kWh, 30 Ah)... except it's in 2 modules.
Electric wizards here surely know if it makes more sense to connect the modules in parallel or series. Assuming parallel, these would be two 80S3P modules with 288 V nominal voltage and enabling to keep riding if one module fails (alternatively, series would be two 40S6P modules with 30 Ah capacity).

Two modules make sense for ease of use, but it likely complicates many other things, not to mention cost.



This is very elegant.



Glad to see new contenders.
Timeline seems very distant.


It has side-mounted radiators.

The bike is a bit ''fatter'' than a Stark. In both a bit more weight as in the panels.

However the battery swap system is really clever. You don't need to lift it all the way out so you will just lift it when it's on top of the bike.
Also they left a lott of room under the seat where normally an airbox would be. And i mean A LOTT of room. I think one could have 2 spare tubes, tools and lunch in there. Or a charger unit.

This swappable battery's that you can also charge outside the bike + the room under the seat to bring stuff make it more ''leasure'' Enduro ready than the Stark is.
Sure the Stark is lighter and slimmer, but i've so far experienced that taking a Stark on longer Enduro rides is challenging and even the portable charger would be a pain to bring in a backpack on a more adventurous Enduro trip.

Just curious... Is each "half pack" half the voltage and they are connected in series? Or is each half pack full voltage and they are in parallel?

It depends on how they did it. If each "half pack" is full system voltage then it does indeed increase system cost and complexity. If each "half pack" is half voltage and they are connected in series, then the addition cost and complexity penalty is not so much.

For the RE Him-E each "half pack" is full system voltage. The bike basically has two battery packs in it.

Regardless. They now weigh 22kg each. Imagine that would be 42kg for one. Now lift that on top of the bike.
Also when building and maintaining the thing. 25kg is the max people are allowed to carry for their job in most EU countries. Coincidence? I don't think so.
