DONT BUY THEIR PRODUCT the Battery is DANGEROUS!
DONT BUY THEIR PRODUCT the Battery is DANGEROUS! I’ve never dealt with a company that works this hard to avoid honoring a warranty. I reported a failing Adria26 battery more than a month ago, well within the warranty period. The bike was 8 months old, fewer than 600 miles, and the battery was shutting off at half charge — a clear defect. Tuttio ignored the issue for weeks, then resurfaced with a canned message claiming “performance may decrease under high load” and offering me a $379 ‘discounted’ replacement instead of honoring the warranty. They didn’t address the defect, didn’t acknowledge the documentation I provided, and didn’t offer an RMA. It feels like they’re intentionally dragging this out to run down the clock so they can say the warranty expired. That’s not customer service — that’s avoidance. If you’re thinking about buying from them, be aware: once they have your money, support becomes slow, dismissive, and focused on upselling instead of fixing legitimate problems. Follow up to this review. Follow‑up: Their private email response that I just received directly contradicts their public claims. Despite what they wrote here, they still refused to acknowledge the defect, repeated the same inaccurate technical explanations, and continued to avoid honoring the warranty. The difference between their public posture and their private handling of the issue speaks for itself. Follow up 4/30/26 My Adria26 battery began shutting off at half charge. I reported it over a month ago, well within warranty, with full documentation. Tuttio ignored the issue for weeks, then resurfaced with the same scripted message over and over: “Please ride the bike until it shuts down and send us a video.” I live in NYC. A sudden power cut in NYC traffic isn’t a “test” — it’s a crash waiting to happen. No responsible company asks a customer to recreate a dangerous failure on purpose. Instead of processing the warranty, Tuttio keeps stalling and repeating the same request, which looks like an attempt to drag this out until the warranty expires. Buyers deserve to know what after‑sales support really looks like here, please read their 1 star reviews as they all seem to have the same theme. Update as of 5/5/26 I've provided all the videos they requested and now nothing but silence from them as they want me to buy a new battery instead of honoring their warranty. “This is my experience with the Tuttio battery after five weeks of attempting to get warranty support. The battery began failing at only 7 months old with under 600 miles of very light use. Tuttio advertises a one year warranty and ‘service after the sale,’ but they have not honored either in my case. I provided all requested documentation and two videos on 5/3, after multiple earlier delays, and have still not received a replacement or confirmation of shipment. Communication has been inconsistent, with repeated stalls and no follow through. The warranty process has not been upheld, and TUTTIO has not stood behind its product or its stated support commitments. The battery shuts off at mid charge under light load, which is consistent with a BMS or cell group failure. I am posting this so other buyers researching this brand can see real world product reliability and the level of support provided after purchase.” “Both warranty videos (‘Adria Fail 1’ and ‘Adria Fail 2’) were viewed by TUTTIO on the morning of 5/4 at 8 AM EST. Although they have not acknowledged receipt or viewing, the links I provided were accessed. No shipment or follow up has been provided as of 5/5. This marks five weeks since the initial claim and one full business day after they reviewed the evidence.” Unfortunately I can not post a video or link here so I guess is off to Youtube. 5/27/2026 I’m updating my original review now that the replacement battery has arrived and I’ve had time to test it. First, here is the message I received from Tuttio Sport after my negative review went live: Greeting： Glad to receive your reply. We have arranged a replacement battery for you.
