DIY vs Professional E-Bike Conversions: Why Letting Us Do It Is Worth It

Converting your bike to electric can be one of the most rewarding upgrades you make — but only if it’s done properly. While some riders attempt a DIY e-bike conversion, there are many technical challenges that can lead to poor performance, safety issues, and expensive mistakes.

At E-MY-BIKE, we’ve converted hundreds of bikes across the UK. In this post, we explain exactly why letting us handle the conversion results in a safer, cleaner, and longer-lasting setup - and why DIY kits often don’t deliver what they promise.

1. We Don’t Just Bolt Things On -

We Engineer It Properly

Most DIY kits come with a “universal fit” approach — but no two bike frames are exactly the same.

At E-MY-BIKE, we:

• Securely mount the battery using professional-grade hardware installed directly into the frame (no Velcro or zip ties)

• Custom design and 3D print brackets to ensure perfect fit and alignment

• Fabricate metal brackets and adapters for load-bearing components

• Ensure everything is mechanically secure, centred, and balanced

🧠 DIY kits often rely on straps, misaligned brackets, or glue (yes, we’ve seen it!).

2. Drink Bottle Mounts Aren’t Strong Enough

Many DIY installers simply attach the battery to the frame using the existing bottle cage mounts — but these are only designed to hold a water bottle, not a multi-kilo battery.

The result? Over time:

• The battery comes loose or rattles

• The frame can crack under stress

• Or the mount shears completely, damaging both the bike and battery

🧠 One misaligned drill hole, or using the wrong mount point, and it’s game over for your frame. We use proper structural mounting methods designed to take the load safely.

3. We Modify Cables and Wiring the Right Way

Cheap kits assume you’ll tuck wires where you can - but this can lead to:

• Cable damage

• Water ingress

• Poor performance

• Untidy or unsafe routing

We take the time to:

• Cut and solder cables to the correct lengths

• Add protective tubing and heat shrink

• Route wiring neatly and safely

• Ensure the display, sensors, and controls are positioned for comfort and visibility

🧠 Good wiring isn’t just about looks - it’s critical for performance and reliability.

4. We Calibrate Everything for Real-World Use

A powerful mid-drive motor is only as good as its setup. We:

• Precisely mount the mid-drive motor to avoid drivetrain stress

• Align the chainline for smooth shifting

• Configure the settings to suit your weight, terrain, and riding style

• Test ride every bike before it goes back to you

🧠 Many DIY installs look good at first but develop issues quickly - grinding gears, loose mounts, and poor battery range are common.

5. We Fix What DIY Kits Often Get Wrong

We’ve seen hundreds of DIY installs that didn’t last:

• Undersized batteries

• Burned-out controllers

• Poor cable splices

• Motors fitted poorly to the bottom bracket

In many cases, the customer spends more fixing or replacing than they would have with a professional install.

6. Peace of Mind with Every Build

When we do your conversion, we:

• Use only quality, tested components

• Offer a 2-year fittings warranty

• Provide lifetime support if anything goes wrong

• Make sure everything is road-legal, safe, and professionally finished

🧠 It’s not just about making it electric — it’s about making it reliable, safe, and fun to ride.

Final Thoughts: DIY Might Be Cheaper, But It’s Rarely Better

A DIY kit might look like a bargain on paper - but without the right tools, engineering, and experience, it’s easy to end up with something underpowered, unsafe, or just plain awkward to ride.

With E-MY-BIKE, you get:

• Professional fitting

• Custom mounting and fabrication

• Clean wiring and system integration

• Ongoing support and peace of mind
