FAQ
FAQ
E-Bikes
Is it legal to ride electric bikes on the roads in the UK?

Is it safe to ride an electric bike in the rain?
Yes, the e-bikes we sell are safe for riding in the rain and going through puddles. Please take care with electrical parts when cleaning — power washers are not advised for any bike.
Can I ride my e-bike like a regular bicycle?
Yes, electric bikes can be used as conventional push bikes, engaging the motor for assistance only when needed — such as climbing a hill.
Do I have to remove the battery for charging?
Please refer to individual product descriptions. If in doubt, drop us a message.

What is the difference between Comfort, Premium, First Class, and Royal Baseground editions?
Our Salta trampoline range is tiered by build quality and features. The Comfort Edition is our entry-level range offering great value. The Premium Edition steps up with enhanced padding and frame quality. The First Class Edition is our top above-ground model with superior springs and safety features. The Royal Baseground range is designed to sit at ground level, offering a sleek, low-profile look and added safety — ideal for younger children.

InGround trampolines are installed flush with the ground, sitting in a dug-out pit in your garden. They offer a cleaner aesthetic and a lower fall height, making them a popular choice for families. Please note that installation requires ground preparation.

Most of our trampolines include a safety enclosure net as standard. Royal Baseground models without enclosure are also available. Please check individual product listings for details.

Age and weight limits vary by model. Please refer to the individual product description for specific guidance. As a general rule, Royal Baseground and InGround models are well-suited to younger children due to their lower height.

About Us
About Us
Straight Spoke is a year-round family adventure store built to help people get outdoors, stay active, and enjoy life together.

Our Story
The idea for Straight Spoke started with a simple frustration — finding well-designed, practical cycling products that actually suited real people, not just specialist riders.
As cycling enthusiasts ourselves, we experienced first-hand how powerful electric bikes could be in everyday life. What started as commuting and leisure soon became something bigger: a way to explore more, move more, and enjoy the outdoors more often.
When we moved to Cambridge, UK that idea grew even stronger. Cycling wasn’t just transport there — it was a way of life. Bikes filled every street, path, and green space. It felt natural to build something within that culture.

So we did.
We started with e-bikes, with a particular focus on accessible, low step-through small frames — because they were surprisingly hard to find, yet essential for so many riders. From there, the range naturally expanded to include solutions for different riders, different families, and different stages of life.
Eventually, that thinking extended beyond cycling entirely.
If movement is good, and outdoor time is better, then why stop at bikes?
Our Journey
🚲 2024 | The Beginning
Straight Spoke started with a passion for cycling and a belief that electric bikes could help more people enjoy the outdoors, commute differently, and travel further with confidence. Our first collection focused on adult e-bikes, carefully selected to suit a wide range of riders and lifestyles.

🚴 2025 | Growing the Family
As our community grew, so did our range. We introduced kids' bikes and ride-ons, helping younger adventurers discover the freedom, confidence, and fun that comes with life on two wheels. What began as a cycling store was becoming a family destination.

🌳 2026 | Ride. Play. Explore.
In 2026, we expanded beyond cycling and embraced a bigger vision: active family living. Trampolines, climbing frames, and camping gear joined our range, bringing even more ways for families to stay active, play outdoors, and create lasting memories together.

✨ The Future
We're just getting started.
Our goal is to build the UK's favourite year-round family adventure store, continually adding new ways to help families get outdoors, stay active, and enjoy more time together.
The path ahead is full of possibilities, the journey continues...

Our Vision
We believe family life is better when it’s active, shared, and outdoors.
Our long-term vision is a world where everyday leisure is less screen-focused and more movement-led — where gardens become play spaces, weekends become mini-adventures, and activity becomes part of normal life again.
We care about practical sustainability too. Many of our products support lower-impact transport, healthier lifestyles, and longer-term wellbeing — for both people and the environment.
But above all, we care about simple things: getting outside, staying active, and doing it together.

Why Choose Straight Spoke
We’re straightforward by name and by nature.
We believe buying online should feel clear, honest, and human. No noise, no confusion — just well-chosen products that genuinely fit real family life.
As a family-run business, we understand that everyone’s needs are different. A lightweight step-through e-bike for easy city travel. A stable all-terrain bike for weekend exploring. A safe first bike for a child. Or a trampoline that turns a garden into a favourite place on earth.
Different people. Different stages. One shared idea: move more, enjoy more, together.

Straight Spoke is no longer just an e-bike store. It’s a growing world of active family living.
