The battery has lengthy been the weak hyperlink of the electrical bike. It degrades within the chilly, ages poorly with quick charging, and infrequently survives greater than 4 years of heavy use. Ride1Up thinks it has a repair – and it is priced it for normal individuals.
The California-based model has launched the Revv1 evo, a moped-style ebike constructed round a semi-solid-state battery that is billed as the primary with this chemistry to be made out there to mainstream US customers at an accessible worth level.
That declare deserves a small asterisk. Fashions just like the Dimentro DP-Pro and the Naxeon I AM – extra motorbike‑like than what riders usually consider as an ebike – had already included semi-solid-state batteries earlier than the evo’s launch, and part suppliers like Joycube and T&D had been delivery comparable packs to different manufacturers for months. What does appear extra defensible is that the evo is the primary moped-style ebike with this battery chemistry out there for direct buy.

So what’s a semi-solid-state battery, precisely? Consider a regular lithium-ion battery as a sponge soaked in a flammable liquid – that liquid is the electrolyte, the medium that lets ions journey between the 2 electrodes throughout charging and discharging. A semi-solid-state battery replaces that liquid with a gel or a low-liquid combination, which reduces hearth threat and improves chemical stability below excessive situations. This isn’t the identical because the fully solid-state batteries that electric-vehicle producers have been promising for years however have but to succeed in mass manufacturing. Semi-solid-state is a center step: safer and extra sturdy than standard lithium-ion, however with out the manufacturing complexity that also blocks full solid-state expertise from scaling.
Ride1Up claims that the Revv1 evo’s battery survives greater than 1,200 cost cycles earlier than dropping to 80% of authentic capability. A typical lithium-ion pack usually hits noticeable degradation round 500 cycles. For a rider charging three or 4 instances per week, that is roughly 8-10 years of use versus the same old 3-4. The bike additionally helps a full cost in two hours – and in accordance with Ride1Up, with out the same old penalty. In standard batteries, fast-charging generates extra warmth that accelerates put on; the semi-solid-state chemistry, the corporate says, handles it extra gracefully. In excessive chilly, all the way down to -20 °C (-4 °F), the ebike’s battery reportedly retains round 70% of its capability, not spectacular however a significant enchancment over the erratic habits of standard lithium-ion cells when temperatures drop arduous. Per-charge vary is reported to be between 30 and 60 miles (48 – 96.5 km).

The evo is constructed on Ride1Up’s current Revv1 platform, shared with the DRT and FS fashions. It packs a 750-W motor with 100 Nm (73.7 lb.ft) of torque and pedal-assist to twenty-eight mph (45 km/h), DRT-spec suspension, and Vee Huntsman all-terrain tires, managed by an onboard battery administration system that the model says actively displays pack well being on each cycle.
The entire thing weighs round 90 lb (41 kg) – nearer to a gas-powered moped than a standard ebike. Meaning it is constructed for open roads and longer commutes, not for locking up at a motorbike rack or hauling up a stairwell. In the event you’re on the lookout for one thing to exchange your automotive on a metropolis commute, this mannequin might make sense in some situations. If you would like a motorbike you may carry into the workplace or condominium, look elsewhere.
At US$2,395, the Revv1 evo undercuts opponents which have adopted semi-solid-state chemistry – equivalent to German model Nicolai, whose upcoming semi-solid-state e-mountain bikes goal a premium section at significantly larger costs. Pre-orders are open on Ride1Up’s web site, with delivery anticipated from August for the US market solely.
The actual story might not be this single bike however what its worth indicators in regards to the maturity of semi-solid provide chains. When a expertise that spent years confined to high-end prototypes and boutique fashions turns into viable at a mainstream worth level, different manufacturers are inclined to observe shortly.
