Thunderbike Rumble Bee • Custombike & Harley-Davidson Gallery

It's off to the second round!

With the Rumble Bee, we show how cool a street bob conversion can look – and with manageable effort. The star of the show? Our new bolt-on rear fender!

For fans of the slim look, we also have a variant on offer that fits the 150 series wheel of the Street Bob. We recommend the Dunlop D401 or the Michelin Scorcher 21 in 150/80B16 on a 3.00×16 rim – so everything fits like a glove. And if you want to mount the rear light directly on the fender, we have developed a suitable milled part that can be attached with three screws. The indicators, on the other hand, are concealed in the struts using the bright Atto indicators from Kellermann. With our license plate holder, we attach the license plate to the side. Thanks to the new, lightweight design, it fits perfectly into the overall picture.

The Strike indicators make the front look delicate

A cool custom bike in just a few simple steps

The small Atto indicators and the rear light shine brightly

We also fitted new indicators at the front and replaced the bulky original indicators with our small stripes, which we mounted inconspicuously under the dashboard. The rest of the front remains original!

A swinging rear fender means a swinging seat

You can’t have one without the other. If we install the swinging rear fender, we also need the matching seat mounting kit. The kit for the titanium seat is easy to fit and has a cool old-school look thanks to the imitation springs. The cowhide swinging saddle with vertical stitching rounds off the whole thing perfectly and enhances the bike. The sound is provided by the Jekill and Hyde flap exhaust system with Jekill Bomb silencers and Slashcut end caps. This makes the Rumble Bee sound richer!

Turn a Street Bob into a really cool bike with just a few modifications? The Rumble Bee shows how it’s done. Bolt on and ride.
