New prosimo report: A TÜV report for the entire classic Vespa-World
There are moments you work towards for a long time. Moments when unpacking a box suddenly means more than just receiving mail. It was exactly such a moment when our latest edition of the TÜV NORD report here with us in Springe arrived – fresh off the press, complete, and this time truly for everyone.
What is contained in this report?
The prosimo report (No. 8123502920, issued by the IFM – Institute for Vehicle Technology and Mobility, TÜV NORD, April 14, 2026) is the official basis for the legal approval of our conversion kits for use on German and European roads. It forms the basis for individual vehicle testing according to § 19 para. 2 or § 21 of the German Road Traffic Act (StVZO) by an officially recognized expert.
What makes this document special: It includes all three classic Vespa-Platforms in a single approval.
Option 1 – Smallframe: From the V50 and the early PK models, through the 90s Super Sprint, to the Primavera ET3. The entire range of small motorcycles. Vespas, which has enjoyed cult status for decades.
Variant 2 – Largeframe: PX 80 to PX 200, Sprint, Rally, 125 GT, GTR, GTS – and also the LML Star models, which are technically based on the same platform. If you ride a PX, you're in.
Variant 3 – Wideframe: The old guard. Vespa 98, the early 125cc and 150cc models, the GS models, the Augsburg GL, ACMA, Hoffmann, Messerschmitt. Vehicles that are older than some grandfathers.

The kits: from 40 to 100 km/h, one motor
Technically, the report proposes five speed options: 40, 45, 50, 80 and 100 km/h.
The batteries vary depending on the kit variant: The Kit-50, Kit-80, and Kit-100 versions, which are rated for speeds up to 80 km/h, use a 50,4 V, 30 Ah Li(NiCoMn) battery. The Kit-100, rated for 100 km/h, uses either a 72 V, 48 Ah battery (Smallframe) or two 72 V, 30 Ah units (Largeframe), depending on the frame type. The battery is located under the seat, connects via a plug/twist connector system, and features an integrated battery management system.
The drive is direct via the wheel hub motor on the rear axle – no gearbox, no chain, no additional wear parts. The prosimo double-sided swingarm with shock absorber replaces the original swingarm on axle 2 and is also part of the approved conversion package.
What "unique worldwide" specifically means
There is no other supplier worldwide that offers electric conversion kits for classic cars. Vespaa comparable, officially recognized type approval certificate – one that combines Smallframe, Largeframe and Wideframe in a single document, issued by an officially recognized Technical Service (KBA – P 00004) and forms the basis for a proper individual approval according to StVZO.
This means for the customer: no gray areas, no DIY projects, no need for an individual assessment on their own. Anyone installing a prosimo kit has a clean basis for TÜV approval – with everything included. The certificate is included with every kit.
What's next?
On our YouTube channel, we've released a new short video showing how the expert report is structured and what it contains. If you'd like to know more – what tests underlie the document, how the structure of variants and versions works in practice, and what an expert checks during acceptance testing – please feel free to leave us a comment. We're planning a more detailed video on this topic.
Until then: The report is in. The range is complete. The classic Vespa Electricity can be legally used – and that's true across Europe.
