Tern Full Service - Bristol

£140 (+ parts) Full Service on Tern GSD, HSD & Quick Haul

Doesn't your most precious cargo deserve a safe ride?

Your Tern's Bosch motor is about the most reliable part of the bike. That's not marketing — it's genuinely well-engineered, and you very rarely need to worry about it, but what does wear, quietly, ride after ride, are similar components to those found on less heavily-loaded bikes: the chain, the brake pads, the pulley wheel that keeps your chain in tension and running true, the pivots on the stand your bike leans on when you're at the School gate. 

Carrying an extra 20-40kg of children, bags and shopping is exactly what your Tern was built for. It's your brakes and drivetrain that pay the price — wearing faster than the Bosch motor ever will. They're the parts that need to be reliable when you're pulling away from a busy junction with your children on board. My experience on eBikes suggests that these parts need to be safety-checked and maintained more frequently than on a lighter bicycle with no electric motor.

i'm Richard and i have been a bike mechanic for 17 years and at iLovesMyBike and i'm the only person you'll deal with - i answer your messages, i collect your Tern, i service it, i hand it back, and i'm the one accountable if anything's not right. 

What I check, and why it matters.

Chain and drivetrain. Every pedal stroke stretches a chain very slightly. On a bike carrying real weight, that wear adds up faster than on a normal bicycle — and a chain that's stretched too far can skip or slip under load, which tends to happen at the worst possible moment: pulling away from a stop with weight through the pedals. i measure chain wear with a gauge at every service and replace before it reaches the point of damaging your cassette too — not after.

Disc brakes. Stopping a loaded cargo bike asks more of your brake pads than stopping an empty one. i check pad wear against safety limits every time, and replace before they're marginal, not when they're already worn through.

Tension pulley wheel. This is the small wheel that keeps your chain running cleanly and safely while you ride — easy to overlook, and one of the first things to wear unevenly under sustained load. i check it every service.

Lock-stand pivots. The stand that holds your Tern upright while you load or unload your child takes more daily strain than most people realise. i check for wear and re-grease if it's dry, so it stays solid under you.

Fixings, frame and undercarriage. Before anything else, i clean and inspect the full undercarriage and frame, and make sure every fixing is properly tightened — vibration works bolts loose over time, especially on rougher Bristol streets.

Wheels, spokes and tyres. i check spoke tension and inspect your Schwalbe tyres for wear or anything sharp working its way in.

Emergency puncture repairs. If you break down in central Bristol, i can come out to you. Once you're safely home, i can replace inner tubes or tyres as needed.

On the Bosch motor

Mechanical servicing and repairs on your Tern are available, but Bosch eBike system diagnostics, firmware updates and motor servicing aren't something i can offer yet — but they're coming. In the meantime, the motor is the part least likely to need my attention; everything above is where i focus, because that's where wear actually happens.

Tern also publish their own maintenance schedule, i will aim to meet that standard and even go beyond?

Home Collection & Return isn't yet available for the Tern Full Service, due to their heavy weight, but you can drop it off at my worksop in BS6 by appointment only.
