LARIAU 36V 250W 700C Ebike Hub Motor Conversion Kit

If you’re a regular cyclist looking to breathe new life into your trusty 700C road bike without splashing out on a brand-new ebike, the LARIAU 36V 250W Ebike Hub Motor Conversion Kit could be the perfect solution. Designed specifically for bikes with 700C wheels—common on road bikes, hybrid commuters, and even some city bikes—this kit balances ease of installation, reliable performance, and smart features that cater to both daily commuters and weekend adventurers.

Compatibility & Installation: Perfect for 700C Bikes (Even for Beginners)

The first question most riders ask about conversion kits is: Will it fit my bike? For 700C wheel owners, the answer here is a resounding yes. The LARIAU kit is engineered to slot seamlessly into standard 700C rear dropouts, meaning if you have an older road bike, a hybrid you love, or a city bike with 700C wheels, you don’t have to say goodbye to it.

Installation is a key concern for many—especially if you’re not a seasoned mechanic—but early users praise the clarity of the instructions. “I’m not great with tools—my partner usually fixes my bike—but the step-by-step guide with photos made fitting this kit a total doddle,” says Sarah, a London commuter who fitted the kit to her 10-year-old 700C road bike. “Took me about 90 minutes, and I didn’t need any special gear beyond what was in the box.”

The kit includes all essential hardware: the hub motor (pre-laced into a 700C rim), intelligent controller, LCD display, handlebar-mounted control pad, throttle (optional, depending on the variant), and all mounting brackets and wiring. Everything you need to convert your bike is there—minus the battery (more on that later, but it’s a feature, not a flaw).

Performance: Legal, Smooth Power for Commutes & Adventures

The 250W hub motor is the heart of the kit, and it’s perfectly aligned with UK electric bike regulations. Under the Electrically Assisted Pedal Cycle (EAPC) rules, ebikes must have a maximum power output of 250W and cut off助力 at 25km/h. This kit checks both boxes, so you can ride legally on any road or cycle path—no license, tax, or insurance required.

The 36V system delivers power in a way that feels natural, not jarring. Start-up is gentle (no sudden jerks), and the motor provides consistent助力 as you pedal. For commuters, this means tackling steep bridges or hills without breaking a sweat; for weekend riders, it’s the difference between struggling up a country lane and enjoying the view.

“I live near a 1-in-8 hill on my way to work,” explains Mike, a Brighton-based user. “Before the kit, I’d have to get off and push—now, the motor kicks in smoothly, and I cruise up at 20km/h without even breathing hard.” The motor’s torque (around 40N·m, based on user tests) is more than enough for most UK terrain, from city streets to rolling countryside.

Smart Controller: Customizable Rides & Essential Safety Features

The intelligent controller is where this kit stands out from budget alternatives. It’s packed with features that make your ride more enjoyable, efficient, and safe:

1. 3 Power Modes (Eco, Normal, Sport)

Eco Mode: The most efficient setting, ideal for long commutes. It provides light助力, maximizing battery life—with a 36V 10Ah battery, expect 35–40km of range.
Normal Mode: The sweet spot for daily use. Balances power and efficiency, perfect for city streets or flat country roads.
Sport Mode: For when you need extra oomph—uphills, headwinds, or weekend adventures. It delivers full power, helping you maintain 25km/h even on steep inclines.

“The modes are a game-changer,” says Tom, a Manchester weekend rider. “Eco gets me through my 15km commute, and Sport makes my Sunday rides in the Peak District feel effortless. I switch between them all the time—it’s like having three bikes in one.”

2. LCD Display & Real-Time Data

The handlebar-mounted LCD screen shows critical info at a glance: speed, battery level, distance traveled, and current power mode. It’s backlit for night rides and easy to read in most lighting conditions (a few users note it could be brighter in direct sunlight, but it’s still usable).

3. Safety First

Brake断电: The motor cuts off instantly when you squeeze the brakes—essential for avoiding accidents in busy traffic.
Anti-Theft Alarm: If someone moves your bike without disarming the controller (via the LCD pad), it emits a loud, attention-grabbing alarm. “I leave my bike outside my office every day,” says Emma, a Birmingham commuter. “The alarm gives me total peace of mind—I’ve never had a problem.”
Overcurrent & Overheat Protection: The controller automatically shuts down if it detects a fault, preventing damage to the motor or battery.

Durability: Built for UK Weather & Daily Use

UK riders know that weather can be unpredictable—rain, mud, and splashes are par for the course. The LARIAU kit is built to handle it:

IPX4 Waterproofing: The hub motor and controller are sealed against splashes and light rain. “I rode through a heavy downpour last week,” says Dave, a Leeds user. “The motor didn’t skip a beat—no water got inside, and it still runs like new.”
Robust Construction: The hub motor is housed in a durable aluminum alloy shell, and the controller is encased in a tough plastic box. The LCD display is scratch-resistant, and the wiring is sheathed in protective tubing.
Low Maintenance: Hub motors have fewer moving parts than mid-drive systems, so there’s less to go wrong. Users report no issues after months of daily use—just occasional checks of the wiring and tire pressure.

Battery Flexibility: Choose What Works for You

The kit doesn’t include a battery—but this is a feature, not a flaw. Why? Because it lets you pick a battery that fits your needs. If you already have a 36V lithium-ion battery from an old ebike, you can reuse it. If not, you can choose a capacity that matches your commute:

10Ah: Good for 35–40km (short commutes).
14Ah: Ideal for 50–60km (longer commutes or weekend rides).
17Ah: For 70–80km (all-day adventures).

Most 36V batteries on the market are compatible—just make sure they have a discharge rate of at least 10A (the kit’s manual lists recommended specs). “I wanted a battery that fits in my bike’s frame bag,” explains Lucy, a Bristol user. “The kit’s flexibility let me pick a slim 36V 12Ah battery that fits perfectly—no bulky racks or bags.”

Value: Save Money & Keep Your Favorite Frame

The biggest selling point for many users is the value. A new mid-range ebike costs £1,500–£2,500; this kit costs a fraction of that—especially if you have a frame you love.

“My old road bike was in great shape, but I needed a little help with hills,” says Claire, an Edinburgh user. “This kit cost a third of what a new ebike would, and now my bike feels brand new. I’ve been riding it every day for three months, and it’s never let me down.”

For riders who have an emotional connection to their bike—maybe it’s a gift, or it’s been with them for years—converting it is priceless. You get the benefits of an ebike without losing the bike you know and love.

Minor Quibbles (But They’re Not Deal-Breakers)

No product is perfect, but the LARIAU kit’s downsides are minor:

No Battery: As mentioned, this is flexible for most, but if you don’t have a battery, you’ll need to buy one separately.
LCD Brightness: A few users wish the display was brighter for sunny days, but it’s still readable—just tilt it slightly to reduce glare.
Throttle Placement: Some riders find the throttle (if included) a little bulky, but it’s easy to adjust or remove if you prefer pedal-only助力.

What Users Are Saying

Early adopters are raving about the kit—here’s a snapshot:

“I’m not mechanically inclined at all, but the instructions were so clear. I fitted the kit to my 700C hybrid in an hour and a half. It’s transformed my commute—I used to take the bus when it rained, but now I ride every day. The power modes are brilliant!”
— Sarah, London

“I’ve had the kit for four months, and it’s been faultless. The motor is quiet, the controller is easy to use, and the anti-theft alarm is a lifesaver. I’d recommend this to anyone who wants to keep their old bike but needs a little help.”
— Paul, Cardiff

“The best part? Legality. I was worried about breaking the rules, but the kit’s compliance with UK law was a huge relief. I ride to work every day, and I never have to worry about getting pulled over.”
— Mike, Brighton
