The Tribe Evamos Longtail now ships with a 13Ah battery. It used to be 10.5Ah. That takes it from 375Wh to 468Wh, which is about 25% more energy on board, and the price has not moved. It is still $3,990.
In practice that is up to 50km on a charge, up from 40km. Range always depends on the load, the hills and how much assist you use, so treat it the way you would a fuel economy sticker. But the direction is not in doubt: it is a quarter more energy, in the same bike, ridden the same way.
Why we have not put the price up
Let us be straight about this, because it would be easy to dress it up as generosity. This bike costs us more to build than it used to. Our margin on the Evamos is smaller than it was. Nothing about this got cheaper for us.
We did it because 375Wh was starting to look small. Battery capacity across the category has crept up. A family comparing longtails is reading the number on the spec sheet, and ours was becoming the small one. That is a fair thing for a buyer to notice, and the right answer was to fix the bike rather than argue about it.
Putting the price up would have made it pointless. An upgrade you pay for is not an upgrade, it is just a different product at a different price. The point of this one is that the capacity goes up and the number on the price tag does not.
We would rather carry it than sell you something behind. We are small enough that a thinner margin on our most popular bike is genuinely felt. We looked at it and decided it was worth it. Good value is not something we do when it is easy, and this was one of the times it was not.
Two safety standards, both real
The new pack is tested to EN50604, the European safety standard for light electric vehicle batteries.
Before anyone with an earlier bike worries: the 375Wh pack is tested to UL2849, the American standard for e-bike electrical systems. Both are proper standards with proper laboratories behind them, and this is not a ranking. UL2849 looks at the electrical system as a whole, the battery and charger and motor together. EN50604 looks hard at the battery pack itself. Different scope, same seriousness.
What both are testing for is the same thing: how the pack behaves when things go wrong. Overcharging, short circuits, crushing, vibration, temperatures well outside anything you would meet on a school run. A pack that passes either one has been deliberately mistreated in a laboratory and did not become dangerous.
You have probably read about e-bike battery fires. They trace back to packs that were never tested to any standard at all, to mismatched chargers, and to damaged cells left on charge overnight. That has never been what we sell, and it is not what is on your bike now.
If you already own an Evamos
This is the one place where we cannot say “and this applies to you too”, so here is the plain version.
The two batteries are not interchangeable, in either direction. If your Evamos was bought before 26 July 2026, the 375Wh pack is your battery and the 468Wh will not fit it. If your bike is from 26 July onwards, it came with the 468Wh and the 375Wh will not fit that one. So when you order a spare, the date you bought the bike is the only thing you need to check.
There is an upside if yours is an earlier bike. We have a surplus of 375Wh packs and have dropped them from $399 to $249 to clear them. Same UL2849 tested pack your bike came with, at the lowest price we have ever put on one. If you have been thinking about a second battery for the school run, now is the time, and we would rather they were on bikes than on our shelf.
Anything else change?
No. Same motor, same frame, same Shimano Cues 9-speed, same brakes, same everything else. This is one component doing more, in the same bike, at the same price.
