Explore our export-ready, CE-certified lightweight inner tubes and precision accessories calibrated for urban couriers, road racing clubs, and all-weather commuters throughout the Kyiv metropolitan area.
Traditional vulcanized butyl rubber tubes exhibit inherent molecular hysteresis, resulting in excessive rotational weight, higher rolling resistance, and sudden catastrophic deflation under high pressure. Our custom polymer extrusion provides quantifiable performance enhancements verified in our testing laboratories.

Operating a bicycle fleet, retail shop, or regional distribution hub in Kyiv demands components capable of handling unique geographical and infrastructural challenges—from historic cobblestones to seasonal temperature extremes.
Kyiv’s central districts—such as Podil, Pechersk, and the steep grades of Andriivskyi Descent—feature demanding historical paving. Our TPU tubes feature superior elasticity and rebound characteristics, reducing the occurrence of "snakebite" pinch flats by up to 70% when crossing granite setts and asphalt transitions.
Winter operations in Ukraine frequently plunge down to -20°C, followed by warm, humid continental summers exceeding +32°C. While standard butyl compounds harden, crack, or leak at the valve junction, JORV TPU maintains mechanical flexibility and airtight seal integrity across extreme seasonal shifts.
With high demand on courier deliveries (Glovo, Bolt Food, and local humanitarian distribution), cargo bicycles carrying heavy payloads need lightweight wheels to save rider energy. Our 20" cargo and 700x38C tubes reduce rotational inertia, allowing delivery personnel to accelerate faster with less fatigue.
Understanding shifting consumer purchasing patterns and municipal trends helps distributors optimize catalog inventory and increase margins.
Fuel volatility and urban congestion have accelerated e-bike and commuter bike adoption in Kyiv and suburban corridors (Irpin, Bucha, Brovary). Since e-bike wheels are heavier, replacing bulky butyl with TPU cuts unsprung rotational weight, improving battery range and handling.
Freight space across European cross-docking centers (such as Warsaw and Chełm into Kyiv) remains at a premium. TPU inner tubes require 70% less packaging volume than rubber counterparts, allowing Ukrainian retailers to stock significantly more units per shelf meter while lowering landed import shipping fees.
Kyiv’s competitive road racing and gravel community actively maintains off-season form through smart trainers and indoor rocker plates. High heat tolerance on direct-drive rollers makes TPU tubes a reliable choice for mixed indoor-outdoor performance athletes.
Founded in 2017 by passionate cycling engineers, JORV combines modern materials science with automated production lines. We do not simply rebrand commodity items; we develop proprietary tooling, inspect every batch, and optimize global logistics.
Headquartered in Qingdao with our European R&D center in Düsseldorf, Germany, a branch in Shenyang, and supply-chain operations in Taiwan. Over 30% of annual profits are reinvested into research and tooling development.
Our 2,000m²+ facility uses automated thermal welding and continuous laser diameter gauges. This keeps our tube walls uniform (down to 0.3mm), eliminating micro-porosities and weak seams.
We lower international wholesale barriers with a flexible 20-piece MOQ per tube specification, 10 pieces for valve stems, and single-unit orders for workshop display equipment and rocker plates.
Every inner tube model and cycling tool is tested to comply with European General Product Safety Regulations (GPSR), ISO 4210, and REACH chemical standards for export into Ukraine and the EU.
Complete private-label printing, custom Ukrainian-language retail packaging, bespoke valve lengths (45mm, 65mm, 85mm), and bundled self-adhesive repair kits tailored to your brand.
Experience handling cross-border cargo routing via Poland or Romania into Kyiv customs terminals. Average customer response time is maintained under 13 hours across international time zones.
Direct from our manufacturing cleanrooms and assembly centers to ensure transparent, dependable B2B supply lines.
