CrossWorx has added a new headline option to its full-power PACE290 platform, and it is useful for existing buyers as well. The CrossWorx PACE290 800Wh battery upgrade is positioned as a straightforward retrofit for riders who already own the bike with the 600Wh pack, giving existing PACE290 owners a factory route to higher capacity without changing the frame.

In practical terms, CrossWorx is adding Bosch’s PowerTube 800 to the menu, alongside the original PowerTube 600, with the bike also set up to work with Bosch’s bottle-style PowerMore 250 range extender. That means CrossWorx can talk about four capacity points on the same platform: 600Wh, 800Wh, 850Wh (600Wh plus PowerMore 250), and 1050Wh (800Wh plus PowerMore 250). If you ride big UK days where battery management becomes part of the ride plan, the CrossWorx PACE290 800Wh battery upgrade is an easy story to understand: same bike, more energy on board, and the option to go even further with a range extender when you need it.

CrossWorx builds frames and bikes in Thuringia, Germany, and sells the PACE290 as either a frame kit or a complete bike via its online configurator, with the new battery option now baked into that setup. If you want the wider context on how to stretch the range on longer rides before spending money, Electric MTB UK’s guide on how to get more range from your e-MTB battery on UK trails is a good starting point, this upgrade is the hardware answer when riding style and route planning are not enough.

CrossWorx PACE290 800Wh battery upgrade for existing bikes: what’s included and what it costs

For existing owners, CrossWorx says any PACE290 supplied with a 600Wh battery can be retrofitted to the 800Wh PowerTube. The company plans to sell a Bosch PowerTube 800 bundle that includes the battery plus the required battery cover for the 800Wh fitment. CrossWorx is offering a clear price of €899 for the retrofit package.

That detail matters because it indicates that CrossWorx is treating the 800Wh option as a supported, engineered change rather than an owner-led parts swap. The battery cover is the key physical piece, because PowerTube sizes and shapes can differ across generations and capacities. CrossWorx is effectively telling current PACE290 owners: this is the kit, this is the price, and it is intended to work.

For riders planning very long days, CrossWorx also offers a second PowerTube 800 as part of a bundle with a complete bike or frame kit for €799. That is not a retrofit headline in itself, but it signals that the brand is thinking in “tour day” terms, where the ability to swap batteries quickly can matter as much as total capacity. CrossWorx also highlights a removable down tube cover to make battery changes quicker, which is relevant if you do want to treat the PACE290 like a big-day platform rather than a single-loop trail bike.

If you are shopping for a new bike rather than retrofitting, CrossWorx states that the PowerTube 800 option costs an additional €250 over the PowerTube 600 option for both complete bikes and frame kits, according to the configurator.

You can see the current options on the official product page for the CrossWorx PACE290, including the newly listed PowerTube 800 option and the PowerMore range extender choice.

How the CrossWorx PACE290 800Wh battery upgrade fits with Bosch PowerMore

The CrossWorx PACE290 800Wh battery upgrade is only part of the range story, because CrossWorx is also leaning on Bosch PowerMore 250 as the “when you need it” add-on. Put simply, the maths is easy: add 250Wh to whatever main PowerTube you have.

That gives the four capacity points CrossWorx is promoting:

600Wh: PowerTube 600
800Wh: PowerTube 800
850Wh: PowerTube 600 plus PowerMore 250
1050Wh: PowerTube 800 plus PowerMore 250

Bosch frames PowerMore as an additional battery that works only on compatible smart system bikes. The key point for riders is that compatibility is not automatic across every Bosch-equipped bike. If you are unsure whether PowerMore can be added or retrofitted to a given model, Bosch recommends first checking compatibility and requirements, typically via the Flow app or a dealer. The clearest reference is Bosch’s help centre page on PowerMore retrofit and compatibility.

For PACE290 specifically, CrossWorx is already treating PowerMore as part of the platform story, with the bike presented as range-extender-ready. In plain terms, the CrossWorx PACE290 800Wh battery upgrade gives you the larger base battery, and PowerMore is the modular “extra” for the longest days or the messiest conditions where higher assistance levels can drain capacity faster.

Availability, lead times, and what UK riders should take from this

CrossWorx says the PACE290 is available to order now as a frame kit or complete bike, with stated production lead times of around four weeks for its Radiant Raw finish and around six weeks for powder-coated builds. For UK buyers, the obvious caveat is that any euro pricing needs to be read in the context of shipping, VAT, and import considerations, but the underlying point remains: CrossWorx is making higher battery capacity a supported choice, and the retrofit kit makes it relevant to existing owners, not just new customers.

From an e-MTB market perspective, the CrossWorx PACE290 800Wh battery upgrade is part of a broader shift toward larger batteries and more modular range solutions. UK riding can be a strong use case for that, because wet surfaces, soft ground, and winter temperatures can increase consumption, even when the average ride distance is low. Bigger capacity is not a magic fix for poor range habits, but it can be the difference between riding the loop you want and riding the loop your battery forces you into.
