The Fatbikeskopen story

Fatbikeskopen B.V. runs several specialist online shops for fat bikes, e-bikes, longtails, folding bikes and accessories, including Fatbikeskopen.nl, Bikeskopen and Gofatbike. Customers compare models online, book test rides at physical locations and get access to a nationwide service and repair network after they buy.

A bike is a considered purchase. Customers compare models, ask about range, availability, financing or delivery, and often want a test ride first. After the sale, the conversation keeps going, from delivery updates to service requests and reviews.

That's why Fatbikeskopen B.V. needed a direct line to its customers, one that connects marketing, advice, purchase and post-purchase communication.

"I think it's a no-brainer for everyone in the e-commerce space to join Chatarmin."

Tom Ouweneel
CEO, Fatbikeskopen B.V.

How did Fatbikeskopen B.V. do it?

Fatbikeskopen B.V. sells an expensive, high-consideration product and handles around 95% of its customer communication over WhatsApp. That used to run across lots of different WhatsApp numbers, and the regular WhatsApp Business app offered no automation. With Chatarmin, everything now runs through one channel, across multiple shops and brands.

Step 1: Build contacts

Prospects send a keyword and get their discount code straight in WhatsApp. Chatarmin attributes every entry, click and purchase to the matching keyword flow. Opt-ins, keywords and discount code flows have brought in more than 80,000 new contacts across the connected accounts.

Step 2: Guide the buying decision

Customers ask about models, range, financing or delivery right in the chat. Anyone who wants to try a bike first requests a test ride via WhatsApp, and a matching flow takes it from there.

Step 3: Win back abandoned checkouts

Shopify reports every abandoned checkout to Chatarmin. The flow checks for the required opt-in, then sends timed messages that lead back to the cart.

Step 4: Automate post-purchase service

Chatarmin connects to the delivery software and sends track-and-trace updates via WhatsApp automatically. Keyword flows answer recurring questions. Everything else goes straight into the customer support software.

The result is one system for lead generation, marketing, advice, commerce and customer service.

"We're close to our customers, and everything runs on one number. Customers reply directly to campaigns and flows, and our customer support is in the chat within minutes."

Tom Ouweneel
CEO, Fatbikeskopen B.V.

The WhatsApp strategy

Win back abandoned carts automatically

Win back abandoned carts automatically

Fat bike buyers take their time and sometimes leave the checkout right before they finish. The abandoned cart flow checks the opt-in and sends timed messages that lead back to checkout. That way, Fatbikeskopen B.V. recovers lost carts automatically.

Use discount codes as a measurable entry point

Connect test rides to the online channel

Many customers want to see and try a bike first. Prospects request a test ride right in WhatsApp, and a matching flow takes it from there. The customer journey stays measurable, even when part of the decision happens offline.

"If I need something, I just send a message in Slack. Before you can even think about it, it's done."
