After being a bigger guy who'd given up on cycling, this Buffalo got me back out there. The 250W motor handles steep hills way better than I expected, and knowing it's built for 150kg gives me real confidence. Battery life is honest - I get 50 miles mixed riding. UK support actually responds. Best purchase I've made in years.

Why Heavy Riders & Hill Climbers Choose the Buffalo
Every component was selected for durability, power, and UK conditions. This isn't a lightweight city bike – it's built for riders who need serious capability.
🏋️
Built for 150kg Riders – No Compromises ⭐⭐⭐
This isn't marketing BS. The Buffalo's reinforced frame, double-wall rims, and heavy-duty components are genuinely engineered for riders up to 150kg (23.5 stone). Forums are full of heavier riders who've had cheap eBikes fail – we designed this specifically to handle real weight without creaking, flexing, or breaking.
🏔️
Hills That Used to Ruin Your Day? Not Anymore ⭐⭐⭐
The 250W high-torque motor delivers 80Nm of pulling power. Yes, it's UK-legal at 250W, but the controller peaks at 500W+ when you need it most – like pulling away from a stop or climbing steep grades. Our customers regularly report tackling 15-20% gradient hills they couldn't dream of before.
🔋
Real 45+ Miles on Massive 17.5Ah Battery ⭐⭐⭐
We're done with brands claiming "80 mile range" that die after 25. The Buffalo's 840Wh battery gives you genuine 45-70 miles depending on terrain, weight, and assist level. At PAS level 2-3 (the sweet spot), most riders see 50+ miles. Samsung/LG cells – not generic Chinese packs that degrade fast.
🛞
Fat Tyres That Actually Grip UK's Nasty Weather ⭐⭐⭐
26" x 4.0" CST puncture-resistant fat tyres provide massive surface area for grip on wet roads, gravel paths, muddy trails, and even snow. UK roads are notoriously rough – potholes, loose gravel, greasy surfaces after rain. These tyres + front suspension = you ride over problems instead of feeling every bump.

Tony R. – Birmingham
Verified purchaser (Direct from BGB)
After months of not cycling due to my weight and dodgy knees, the Buffalo got me back out there. Arrived quickly and setup was straightforward – watched a YouTube video for the headlamp connection. Three months in and I'm hooked. The fat tyres make me feel stable and confident on trails I'd have avoided before. The motor assist on hills is a game-changer. Battery life is solid – I get 40+ miles mixed riding. This beast brought back the joy of exploring outdoors.
Graham M. – Leeds
Verified purchaser (via authorised retailer)
I'm 58 with a bad back from years of manual work. Tried regular bikes but the jolting on rough paths was agony. The Buffalo's suspension (front fork + seat post) changed everything – I can do 20-mile canal towpath rides without back pain flaring up. The thumb throttle is brilliant for getting going from stops without straining. Mix of pedal assist levels means I choose my workout intensity. This bike gave me my freedom back.
David L. – Wales
Verified purchaser (Direct from BGB)
I nicknamed mine 'The Beast' because it absolutely is one. I'm 18 stone and every cheap bike I've tried felt flimsy and underpowered. The Buffalo's frame is solid – no creaks, no flex, nothing rattles even on rough trails. The motor pulls me up 15% gradient hills that used to destroy me. The 26-inch fat tyres grip wet roads like nothing I've experienced. After 6 months and 500+ miles, it still rides like new. Heavy? Yes (30kg). But that's because it's built properly, not some Alibaba tin can.
Robert F. – Scotland
Verified purchaser (via authorised retailer)
I'm 22 stone and was nervous about whether any eBike would actually hold up. I'd read horror stories on Reddit about frames cracking and motors failing on cheaper imports. Three months with the Buffalo and zero issues – frame is rock solid, motor hasn't complained once, brakes still feel strong. I do 25-mile commutes twice a week (hills, flat, bit of gravel path). Battery life is as advertised, not the inflated nonsense other brands claim. Big Game Bikes support actually responded when I had a question about tyre pressure – same day. This is what other heavy riders need to hear: it's genuinely built for us.
Getting Started is Simple

Choose Your Power Level
Start in PAS 1 for gentle assistance (great for fitness), or jump to PAS 3-4 for hills and fast commutes. The throttle gives instant boost when pulling away from traffic lights. The controls are intuitive – even if you've never ridden an eBike, you'll figure it out in minutes.
🔧
Minimal Maintenance
Keep tyres inflated, chain lubed occasionally, and you're sorted. Hydraulic brakes are self-adjusting (massive upgrade from mechanical). Battery lasts 800+ charge cycles. Unlike overseas brands where you're stuck waiting months for a £3 part from China.

Customer Stories
These are real stories from riders who chose the Buffalo through Big Game Bikes or our authorised retailers. They show how different riders are using the bike in real UK conditions.
Peter H.
Leicester
I compared RadRhino, Himiway Cruiser, and this Buffalo for months. Buffalo offered the longest range, UK support, and was in stock (Rad kept delaying). Six weeks in, I've done 200+ miles commuting and weekend rides. The motor handles my 110kg + backpack easily. Battery still shows 2 bars after 15 mile commute. Hydraulic brakes are a must in rain. Very pleased.
Karen M.
Wales
My husband and I both got Buffalos after our old mountain bikes became too much effort (we're both in our 50s with joint issues). These bikes have given us our independence back. We do 20-30 mile loops on Welsh hills and trails. The assist levels mean we can still get a workout but aren't destroyed by steep climbs. Gravel paths are easy with the fat tyres.
Anthony R.
Birmingham
Biggest surprise was the build quality. I expected 'good enough for the price' but it's genuinely solid. Welds look professional, paint is thick, nothing rattles. The weight (30kg) might put some off but that's what you get with a properly built frame and big battery. I'd rather have heavy and reliable than light and creaky.
Jamal K.
London
Use this for deliveries around London. Can load 20kg of cargo on the rear rack no problem. Gets through 8-10 hour days on one charge if I'm smart with assist levels. The throttle is brilliant for getting ahead of traffic at lights. Paid for itself in 2 months vs bus/tube costs. Wish I'd bought it sooner.
Sarah T.
Scotland
Scottish weather throws everything at you. This bike has handled torrential rain, gusty wind, and even some snow. The hydraulic brakes work perfectly in wet (my old mechanical ones would fade). Fat tyres don't slip on wet leaves or mud. The integrated lights are bright enough for dark winter commutes. Properly designed for UK riding.
Robert F.
Cornwall
I'm 24 stone and was nervous about whether this would actually hold up. Three months and 400 miles later – zero issues. Frame hasn't flexed, motor hasn't complained, brakes work fine. This is what other heavy riders need to hear: it's genuinely built for us, not just marketing claims.
Emma P.
Manchester
After a bad experience with a budget eBike from Amazon (broke after 100 miles, seller ghosted me), I researched properly. Buffalo's UK support was the deciding factor. Had a question about battery care, they responded same day with actually helpful info. Bike arrived fast, well packaged. Assembly was easy. This is how it should be.
Marcus D.
Bristol
Coming from a car background, I appreciate when things are over-engineered. This bike is built like it means business – thick frame tubes, beefy fork, proper hydraulic brakes (not cable-pull fake hydraulics). The motor controller is smooth, battery management system is intelligent. You can tell someone who rides bikes designed this.
Helen & Tom
Devon
We tour with our caravan and wanted bikes we could take along. The Buffalo's rear rack holds plenty of shopping when we're at campsites. The fat tyres work brilliantly on campsite gravel and coastal paths. Battery lasts all day if we're touring around. Both bikes have been faultless over a summer's heavy use.
Chris W.
Yorkshire
Yorkshire hills are brutal. This bike makes them manageable. I'm not fit, I'm not light, but I can now do 30+ mile rides I wouldn't have attempted before. The assist feels natural – it amplifies your effort rather than just dragging you along. Shimano gears are proper quality (not the no-name stuff on cheap imports). Happy customer.

Common Questions Answered About the Buffalo eBike
Clear answers to help you choose with confidence and ride worry-free
Is this really road-legal in the UK?
Is this really road-legal in the UK?
Yes. The Buffalo 250W complies with EAPC regulations. This means: 250W rated motor (peaks higher when needed, legally allowed), assistance cuts off at 15.5mph (25kph), pedals must be turning for assist to work. You can ride this on UK roads, cycle paths, and bridleways without tax, insurance, MOT, or a license.
Will it handle my weight? I'm over 100kg / 15 stone.
Will it handle my weight? I'm over 100kg / 15 stone.
Absolutely. The Buffalo is specifically designed for heavier riders up to 150kg (23.5 stone). We've reinforced the frame, used double-wall rims, heavy-duty spokes, and upgraded components throughout. Many of our customers are 90-130kg riders who've had other bikes fail – the Buffalo is built to last under real weight.
Can it really climb UK hills with my weight?
Can it really climb UK hills with my weight?
Yes. The 250W motor delivers 80Nm of torque (pulling power), which is on par with larger bikes like the Himiway. UK customers in Yorkshire, Wales, and Scotland regularly report conquering 15-20% gradient hills. The motor controller delivers peak power (500W+) exactly when you need it most – pulling away or climbing steep grades.
What's the real range? Not marketing fluff.
What's the real range? Not marketing fluff.
Honest answer: PAS 1-2 (low assist): 60-70 miles flat terrain. PAS 3 (medium): 45-55 miles mixed terrain. PAS 4-5 (high assist): 30-45 miles hilly terrain with heavy rider + cargo. The 17.5Ah battery (840Wh) is among the largest for UK-legal bikes. Most customers see 50+ miles in real mixed riding.
How is this better than cheaper bikes on Amazon?
How is this better than cheaper bikes on Amazon?
Three words: Support, Quality, Safety. Budget Amazon/eBay eBikes often use generic motors prone to failure, small batteries with poor cells, mechanical brakes that fade, and sellers who disappear. Buffalo uses CST tyres, Shimano gears, Samsung/LG battery cells, hydraulic brakes, and we're a UK company with actual support. You pay £200-300 more upfront but save £££ long-term.
Is the battery removable?
Is the battery removable?
Yes. The battery slides out and locks securely with a key. This allows indoor charging (no need to bring whole bike inside), reduced weight for lifting (30kg with battery, 25kg without), security (take battery inside), and spare battery option for long tours. Charging takes 4-6 hours from empty.
What's the warranty and what if something breaks?
What's the warranty and what if something breaks?
2-year warranty covers frame, battery, motor, and all major components against manufacturing defects. Email us at hello@biggamebikes.com and we'll diagnose (often fixable with adjustment). If a part is needed, we stock everything and ship fast (UK warehouse). For major issues, we have UK service partners nationwide. Compare this to overseas brands where customers wait 6+ weeks for parts.
What's the returns policy?
What's the returns policy?
30-Day Money-Back Guarantee*. If the Buffalo isn't right for you, return it unused in original packaging within 30 days. We refund your purchase price (minus £125 return shipping for eBikes). You can arrange your own return courier if preferred. Bike must be unused (test rides up to 5 miles okay on private land), no damage, all accessories included.
What maintenance does it need?
What maintenance does it need?
Very little: Every ride – check tyre pressure (20 to 25 PSI). Every 2-3 weeks – wipe chain, add lube. Every few months – check brake pad wear (hydraulics self-adjust). Annually – full service (brake fluid, gear adjustment, bearing check). The battery requires no maintenance. Hydraulic brakes are lower maintenance than mechanical.
How fast is delivery?
How fast is delivery?
