Within the e-bike world, we regularly joke that a few of the beefier and extra large US-market electrical bikes are extra like small electrical bikes. Nicely, a model known as Happyrun will need to have heard us and pulled the ol’ “maintain my beer!” The result’s the Happyrun Tank G100, which can put on a pair of bicycle pedals however is all bike from the ankles up.
Yep, that is a type of particular e-bikes that comes alongside in a uncommon but epic second within the continually evolving North American electrical bicycle market. I don’t imply it’s an awesome bike, however simply that it fills an awesome spot out there.
There’s quite a bit to like about it, however there are additionally some apparent compromises and some authorized gray areas to leap over, Evel Knievel-style.
However as standard, this an e-bike you’ve obtained to see to consider. So check out my evaluation video under earlier than persevering with on with the remainder of the article.

A LOT of motorcycle!
Let’s simply handle the apparent right here first. The G100 seems like a motorbike. Sure, it’s obtained pedals, however they’re what I wish to name vestigial pedals. They’re principally left over from the earlier generations of e-bikes it developed from, however are not obligatory in its present state.
As a substitute, we’ve obtained a motorcycle-lookin’ factor that feels very similar to a motorbike if you hop on it. Not solely is the battery formed like a fuel tank, however the tall entrance fork provides the complete bike a chopper-like feeling that slopes again towards the rear. While you add within the different options like motorcycle-style flip indicators, the bench seat, and the twin coilover shocks within the rear, you’re left with some severe moto cosplay.
And don’t overlook the bike weighs a hefty 107 kilos, which means all of that heavy package contributes to extra than simply the look. Although to be truthful, you get some efficiency with all of that weight, too.
For instance, a bunch of the majority comes from the 2 batteries. That’s proper, there are two batteries on this e-bike. The fuel tank battery is the apparent one, however there’s truly an underslung battery sitting proper beneath it. Collectively, they pack in 48V and 38Ah of pure, unadulterated lithium-ion pleasure.
Then there’s the chunky rear hub motor, rated for 1,000W of nominal energy however a severe 2,000W of peak energy. That’s a part of the explanation you want these two batteries, to provide the facility drained by that chunky motor.

However what concerning the efficiency?
Curiously, the e-bike comes proper out of the field in “off-road” mode, which means I didn’t even need to unlock it to entry the faster-than-legal-in-most-areas speeds. They declare a high pace of 38 mph (61 km/h), however I discovered that I really topped out at extra like 34 mph (54 km/h) on flat floor.
I additionally discovered that whereas the acceleration was fairly good up by round 20-ish mph (32-ish km/h), the facility appeared to decelerate previous that degree. To maintain going to the bike’s high pace took a little bit of ready with the throttle pegged. Nonetheless, making up for the slower top-end acceleration is the truth that the bike can hit these speeds in throttle-only operation. That’s a great factor too, because you’re undoubtedly not going to need to pedal this factor to attempt to unlock the upper pace like a real Class 3 e-bike.
That brings me to the e-bike lessons. Out of the three authorized lessons, Class 3 is the best at 28 mph on pedal help and 20 mph on throttle. And the Happyrun Tank G100 might be restricted to Class 3 operation, however the off-road mode it is available in doesn’t give a flying flip about your native legal guidelines and simply provides you all the facility and pace that it will probably proper out of the field. That’s maybe a bit irresponsible because you by no means know who’s going to be opening that field, and I’d fairly see them no less than make the rider undergo some semblance of an unlocking process that will make it tougher for teenagers to succeed in such excessive speeds. On that be aware although, the bike does have NFC playing cards it makes use of to unlock the bike, so in the event you don’t need your child borrowing your bike with pedals, you may simply maintain the cardboard safely in your pockets. In the event that they need to take the G100 out of the storage, they’ll be caught pedaling that heavy bike at 3 mph.

How does it trip?
It weirdly appears like a motorbike. I say “weirdly” since you simply don’t count on it to. Yeah, it seems like one. However if you pop a squat, the way in which your toes are splayed nonetheless makes you’re feeling such as you’re on a motorbike. And but, if you trip it off-road or be taught onerous into the turns, it undoubtedly has extra of a moto-feel than a bicycle really feel.
I’d name the suspension acceptable however not nice. Using off-road is feasible, however I discovered that the saddle would come up and provides me the ol’ one-two perineum punch typically, as if the rebound was simply dialed up method too excessive. In fact, this isn’t very refined suspension, and people piggy-back reservoirs are undoubtedly faux, leaving simply easy spring shocks within the again. I usually discover that e-bikes with twin rear shocks are overly sprung anyway, however I’m a lightweight rider and maybe you’ll sink into that suspension greater than I did.






What concerning the parts?
As a lot enjoyable because the bike is to trip, it’s necessary to do not forget that these are fundamental bike parts right here. The tires aren’t tremendous high-end; they’re simply fundamental Chinese language Chao Yang tires. The derailleur is a cheapo Tourney derailleur. The brakes are DYISLAND hydraulic disc brakes, however they aren’t significantly upper-shelf ones, both.
So, principally, you’ve obtained a rocket of an e-bike that weighs a ton and is driving on mediocre gear. It’s not precisely a recipe for long-term success, that’s for positive.
It really works simply advantageous proper now, and I by no means felt just like the bike was underbraked or something, however none of those components are identified to final for years of carefree driving.
However then once more, it is a $1,699 electrical bike. It’s not a motorbike, and it’s not a high-dollar trip. It’s a budget-minded electrical bike that appears prefer it most likely deserves a rap sheet however no less than is available in at a budget-minded worth. So, nobody expects high-end components right here.
I undoubtedly would advise a severe phrase of warning relating to each the depth of driving and the situation/model of driving. It is a quick bike rolling on non-motorcycle components, and it’s additionally both questionably authorized or undoubtedly not authorized in lots of areas on account of its greater energy and pace specs. So maintain these points in thoughts.
However in the event you’re driving in an space the place it’s acceptable and also you need to have a critically enjoyable time on a motorbike that appears like a one-of-a-kind moped, you’ve discovered the reply proper right here.
Yet another factor
Whereas I did my evaluation on the yellow and black Bumblebee model e-bike, additionally they make a model that’s all ‘MURICA!
I couldn’t assist however borrow one actual fast for the photograph op, both!
