Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Tern Vektron Technology Highlights

OCL+ Frame Joint - Robust folding technology

A heavy-duty update to the iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.

Andros Stem - Adjust to fit

The patented Andros adjustable lets you set your handlebars where you want - no tools, no fuss. In just seconds, you can set your riding position to long and low in a tough headwind, or upright and comfy for riding around decide. You decide how you want to ride, and the Andros makes your bike fit.

Porter+ Saddle - Carry your bike comfortably

Tern have re-engineered the underside of the age-old bike saddle into a comfortable grip and shoulder pad. Up-top the dual-density construction and gel cushioning will keep you comfortable on the road, complete with a waterproof and easy-to-clean vacuum construction. Down below, the GripPad on the underside of the saddle lets you grip the saddle nose with comfortable confidence.

Magura MT4 hydraulic disc brakes - Stop on demand

Powerful brakes that bring you to a confident stop - even in rain, snow or mud. The caliper design is both ridged and durable, and the non-corrosive mineral oil brake fluid is gentler on the environment than most hydraulic brake fluids.

Bosch Active Line Plus Drive Unit - Universal performance

Adapted from Bosch's German-engineered automative applications, the Active Drive Unit can take you up to 25km per hour, and operates dependably - day in and day out. Its high-performance electronics, whisper-quiet operation, and low-levels of vibration are remarkable - especially given the light-weight, ergonomic design.

Bosch PowerPack Battery - Feather-light powerhouse

This impressive high-energy, high power cell clips on and off your bike. The best-in class design charges fast and lets you ride longer and further between charges. You'll be impressed by its long lifespan, light-weight and ease of charging.

Bosch Purion Control Panel - Compact control centre

The Purion on-board computer lets you swtich between five different riding modes, and feeds you handy information like speed, battery level, and distance. It optimises shifting actions and constantly updates you on the remaining range. Best of all, it's now more compact and robust than ever.

Valo Direct Light - Immediate Illumination

The 41 lux, 150 lumen Valo Direct lights up your ride without adding the drag or weight of a dynamo. It's engineered to sit inside the handlebar stem, where it's safe from knocks, bumps, and theft. That means it's protected while folding, and optimally positioned to give you the most light.

One Size 147 - 195cm (4'10" - 6'5") 105kg (230 lbs)

How To Measure Yourself

Measure Your Height

Our handy size charts match your height to the appropriate frame size so you need to be sure you’ve measured your height accurately.

  1. Take off your shoes and stand with your back against a wall.
  2. Make sure legs are together and your shoulders are back.
  3. Place a pencil on top of your head and mark the wall (the best and easiest way to do this properly is with a friend to help you).
  4. Measure from the floor to the pencil mark you have just made with a tape measure.

Range of Reach

For most people to get the right frame size, measuring your height will suffice. However, you may find that your height is on the borderline of the range we suggest for a particular frame. If this occurs you need to measure the range of your reach or “Ape Index”. This will ensure you get a comfortable distance between the handlebars and your saddle.

  1. Stand up straight with your back against a wall.
  2. Life your arms out horizontally either side of you.
  3. Measure the distance from fingertip of one hand to fingertip of the other. This will give you your arm span.
  4. Subtract your height from this figure to get your Ape Index.
  5. If the result is positive (your arm span is greater than your height) you should go for the larger size of bike.
  6. If the result is negative (your arm span is less than your height you need the smaller size.

Stand Over Height

You should also consider your inside leg measurement when choosing your bike to ensure adequate stand over height. Stand over height is the clearance between the top tube and the bottom of your crotch. For mountain bikes we recommend a distance of 2-4 inches and for road or hybrid bikes 1-2 inches of clearance is required. This will ensure comfort when you’re stopped and standing astride the bike.

Our bike sizing charts take stand over height into consideration but if you have a particularly long or short inside leg measurement in relation to your height you will need to bear this in mind when selecting your frame size.

Riding Style

The way you ride and the type of bike you are into will also impact the frame size you should choose. For example, a trail devotee looking for an aggressive ride may prefer a smaller, more manoeuvrable bike size. It all comes down to personal preference and how the bike feels to you.

Our sizing charts aim to be as specific as possible so you can look up the particular type, make and model of bike you’re looking for. Remember, the sizes given in our guides are suggestions and should be used for general advice only. For the best possible fit  we recommend popping in to your local Leisure Lakes Bikes store, or call 0800 083 0888 for expert advice tailored to you.
