Range Confidence That Supports Real Use
The BK28 is built for riders who want fewer limitations in everyday riding. With its 48V 25Ah removable battery (1200Wh), it provides the capacity needed for longer distances, varied terrain and higher assist levels. Instead of planning every ride around battery range, riders can focus more on where they want to go. This makes it suitable for commuting, longer trips and mixed-use scenarios without constant charging concerns.
Designed for Slopes and Mixed Terrain
Many e-bikes perform well on flat roads but feel less stable on slopes or uneven surfaces. The BK28 is designed to handle hills, rough roads and changing terrain with more consistency. It provides a more controlled ride when climbing or navigating less predictable routes, making it a practical option for riders who do not want to limit themselves to smooth urban environments.
Stable and Controlled Riding Experience
The combination of fat tires, suspension and a solid aluminium frame results in a more stable ride. Road vibrations and impacts are reduced, helping the rider stay balanced and comfortable. This improves control on longer rides and reduces fatigue, especially when riding on imperfect road surfaces.
Reliable Braking for Everyday Safety
Tektro hydraulic disc brakes provide more predictable and responsive braking performance. This is particularly important on wet surfaces, downhill sections or in urban traffic situations. The system allows smoother braking control and requires less effort, improving overall safety and rider confidence.
Practical Features That Improve Usability
The BK28 integrates features that make everyday use more convenient. A removable battery allows flexible charging, while NFC unlock and app connectivity simplify operation. The integrated front light improves visibility, and fast charging reduces downtime. Together, these features make the bike easier to use on a daily basis.

A Practical Setup for Everyday Use
The BK28 is designed with usability in mind. NFC unlock, app connectivity, fast charging (5–6 hours) and a multifunction display all contribute to a smoother day-to-day experience. It is a setup built for regular use, not just occasional riding.
Hydraulic Braking for Better Control
On wet roads, slopes or uneven surfaces, braking performance becomes critical. Tektro hydraulic disc brakes provide more consistent stopping power and smoother modulation, helping riders maintain control with less effort. This is particularly important for heavier bikes and real-world riding conditions.
Stable Ride Across Mixed Surfaces
The combination of 20×4.5 puncture-resistant fat tires, front and rear suspension, and an aluminium frame delivers a more stable riding experience. The bike absorbs road imperfections more effectively, helping maintain balance and control across rough or inconsistent surfaces.
Range Confidence for Longer Rides
This is not just about a number on a display. It is about having a battery system that supports longer distances, steeper routes and less predictable riding conditions. The 48V 25Ah (1200Wh) battery is a key part of the BK28’s value, reducing the need to constantly think about charging and allowing more flexibility in daily and weekend use.
Features And Details
Walk Assist Support
Walk assist provides low-speed motor support (up to 6 km/h) when pushing the bike. Particularly useful on slopes or when manoeuvring in tight spaces, helping manage the bike’s weight more easily.
Comfort-Focused Saddle
A wide and supportive saddle (44 × 15 cm) improves comfort on longer rides and uneven surfaces, reducing pressure and fatigue over time.
Multifunction Display
A clear display shows key riding information at a glance, including speed, assist level and battery status, allowing better control without distraction.
Integrated Front Light
A built-in front light improves visibility in low-light conditions, increasing safety on darker roads and evening rides. Designed as a practical, always-available feature
NFC Unlock System
NFC unlock allows quick and simple access without traditional keys, improving convenience while adding an extra layer of security.
20×4.5 Puncture-Resistant Fat Tires
Wide tires improve grip and stability across loose or uneven surfaces. The puncture-resistant construction adds reliability, especially for longer rides.
Hydraulic Disc Brakes
Hydraulic braking ensures consistent stopping performance with less force required at the lever, particularly useful on slopes and in wet conditions.

What people are saying
heb nu een aantal weken de hitway bk28 fatbike in bezit en wat een bike na aankomst netjes in elkaar gezet wat moest vers uit de big box pittig zwaar ook vooral met de chronische ziekte fibromyalgie waarom ik ook deze bike heb aangeschaft ter vervanging van mijn troy diablo eerste basis model zonder vering en maar liefst 36 volt de eerste test rit ging super goed en wat een verschil ook wat werd ik verwend met de bk28 van hitway 48 volt 25ah 1200wh die 80 kilometer op max assist pas 5 al moet ik erbij zeggen als ik meer berg af en vlak terrein had gehad kon er meer uit gehaald worden 90/95/100 max bij echt goede condities weer en terrein het max aan gereden kilometers ligt bij mij bij gemixet terrein bij 82,9 kilometer met nog 20% in de grote jonge van een accu wat een beest ook en weegt wel wat
de bike is echt super stevig frame materiaal is ook best vet dik ook echt kwaliteit bij aankomst zat de voor vering vast dat met wat olie snel verholpen en na email contact wegens een dode lader bij aankomst hebben ze me een nieuwe toe laten komen wat dat betreft laten ze je niet in de kou staan en kon ik nadat de nieuwe lader binnen kwam de accu laden en erna weer flink kilometers maken heuvellandschap grens hoppen Duitsland gravel paden bospaden trails bij dag en nacht bergen op dalen in prachtig gewoon
heb de bk28 wel mijn eigen tintje gegeven ondanks de handvatten die erop zaten en twist gashendel voor boost/walk assist tot 6kmh welke rede is voor aanhouding en test rollerbank deze gedemonteerd netjes en mijn gif groene doodshoofd handvaten erop gezet die geven zacht meer grip en stevigheid en wat zijn ze een looker ook nice bijpassende ventiel dopjes zelfde kleur linker zijspiegel erop motor telefoon houder en een motor front stuur Tactical tas voort geval ik iets meer voor onderweg mee wil nemen eten drinken snacks tech extra licht bronnen voor de nacht tour ritjes en wardriving gps mappen gebieds blokken turf wars kleine hobby zonder mijzelf te veel te belasten is er ook nog de tank handschoenen vak bak daar past ook het nodige in tevens is de klep afsluitbaar de banden van 20/4,5 inch wat een heerlijk breed fijne wegligging erg vergevingsgezind zeker nog met de full suspension front en back weinig last na paar uur int zadel te hebben gezeten aan mijn lijf ik ben 43 jaar 1,73cm lang de minimum hoogte lengte voor deze bike past perfect trouwens en waar mijn 3 jaar oude bike mij liet zwoegen trok de bk28 mij overal moeiteloos doorheen en omhoog en opeens zijn veel meer wegen en paden zoals on en off road te begaan die ik eerst niet in kon slaan met de oude troy is er nu een nieuwe wereld geopend aan wegen trails paden vlak en ruig urban streets en patches bos en tussen de weilanden door ik geniet gewoon dankzij deze bike je valt wel op met deze big boy bike die blikken soms als voorbij rijdt geweldig gewoon en als ik ergens soms stop de vragen die men mij stelt over de bike en zelfs motor muizen die wel even de blik net iets te lang laten tracken op mijn e fatbike die motor look is wel echt een blik vanger wat ik wel mis voor mijn nachtelijke avonturen is dat de koplamp voor de straat super zijn in de stad maar mis dan toch op die duistere plekken waar ik toch iets meer nodig heb dat het niet voldoende is dit loste ik op door een hoofdlamp mee brengen en waar nodig te gebruiken maar iets meer verzicht samen met die breede beam na de zijkanten was wel wenselijk geweest in mijn situatie en ondanks dat de bk28 een 1 zitter is kan er krap iemand achterop die niet te zwaar is maar kijk uit met de voeten er geen plek ervoor verbruikt wel iets meer accu maar de test voor klein blokje om of nood situatie werkt prima zo wel minpuntje de trip meter springt op nul als je de bike uitzet bv even de snackbar in en dan weer door met de rit dan moet even rekenen met de oddo meter foto maken van de stand en achteraf eind foto van de oddo meter en rekenen maar ik had zelf de rit meter willen resetten met een knop int menu ook als je twist gashendel eraf haald werkt de walk assist knop niet meer int menu kun je die aanzetten sterk is het niet zoals met de twist throttle en je moet dan 3x trappen tot de pas assist aanspringt soort beveiliging die enorm stoort dus om dat direct bij 1x trappen aanslaat dan maar geen walk assist dat zijn de enige minpuntjes ow op scherm de % aan accu zou het iets accurater maken dan hoef je de app niet erbij te pakken op de Smartphone om de exacte stand uit te lezen maar kleine moeite met de smartphone aant stuur das wel weer fijn
sinds ik met de bk28 terrein ben aant verkennen geniet ik meer van mijn omgeving en zelfs mijn moeder van 71 wilt een hitway bike hebben en ze heeft eentje opt oog hint 48volt 27ah mic drop 🎤
Learned of this bike via Bacon Butties YouTube channel. I was impressed and after watching more reviews I purchased a BK28. Ordering and payment was straightforward and good communication updates regarding delivery which was on time and by a helpful team who put the bike in the garage for me. Assembly was quite easy using the supplied tool set, although a larger, detailed diagram for the front axle would have been appreciated and locating the saddle screw is fiddly. The brackets for the headlight were on the wrong side of the forks but were easily swapped over. After charging and fitting the battery everything powered up as expected then having properly inflated the tyres it was time for a test ride. Having watched various reviews I had a familiarity with the controls and was immediately impressed with the performance, controllability and comfort. Brakes quickly bedded in and are excellent. It also looks fantastic and for a heavy bike I found I quickly got used to the handling and soon forgot the additional weight compared to my previous bike. I particularly like the front and rear lighting plus brake light and the adjustable suspension. The storage box is a real boon for tools and locks. I have now tried it on roads of variable quality, forest trails and canal towpaths including some steep climbs and am more than impressed, in fact I think the bike could handle more than I could! It would be marvellous if a device for adjusting the saddle height could designed as this would make it a five star machine.
Sehr schönes Fahrrad fährt sich hervorragend. Bin voll und ganz zufrieden. Gruß Jirka Kerl
Well built bike with loads of features, love the design too, I do mostly road cycling so this will be ideal for me.
All i can say is my hitway bk28 is the best bike I have rode she is my little donkey a real work hourse you can get at least 40 miles on a charge more if you do some work my only complaint is I have no headline for my bike yet I look forward to going to work on it please be quick with my headlight brackets you have rely made aa fantastic bike thanks again
