You love the power and practicality of a Bafang BBS DIY conversion — but you want freedom, independence, and a safe, confident feeling every time you ride. That’s exactly what the GutRad StVO Module is built for: a professional hardware solution that brings your conversion onto a clear, compliant pedelec line — so you can ride relaxed instead of worried.

Why this matters

As soon as a converted bike is provided, sold, or put on the market, the situation can quickly shift from “private hobby project” to product responsibility — including typical obligations around safety, documentation, traceability, and potentially CE-related technical files. For one-off builds, proving things like shutdown behavior, electrical safety, EMC behavior, tamper resistance, and conformity can become complex and costly.

And even if you write “private sale, no warranty,” real-world liability risks don’t simply disappear. Add the common trap: many conversions accidentally cross the line where the bike no longer qualifies as a pedelec — which can trigger insurance and legal consequences. That’s stress nobody needs.

The GutRad solution: clear, safe, professional

The GutRad StVO Module is designed to help a Bafang BBS conversion behave like a pedelec setup again — with a strong focus on predictable, compliant operation:

– Supports pedelec-style operation (including 25 km/h pedal-assist behavior and a 250 W nominal continuous power approach in the StVZO context)- Throttle is disabled – less gray area, more clarity

-Built around safety logic, defined cutoff behavior, and a traceable compliance approach

– More confidence in daily life: fewer “what if” thoughts during inspections, after an incident, or when selling a bike

In short: keep the DIY fun — gain peace of mind.

Real benefits you feel

– Freedom: ride without constantly second-guessing your setup.

– Independence: a hardware-based solution instead of risky parameter “tuning.”

– Safety: reduce technical and legal risks with a defined operating concept.

– Confidence: especially valuable if you ever hand over or sell the bike.
