Bikesy's Verdict
Buy a current Torrent e50B if you want Bosch mid-drive help for commuting and mixed-surface leisure, and you will check which build a listing really is. Both latest bikes share the 65 Nm Performance Line motor, 625 Wh PowerTube battery and an up-to-150 km maximum-range claim. Choose the official Tour EE for Easy Entry and the listed mudguards, lights, lock and kickstand in S, M or L. Treat a retailer 1x8 Touring label as a different bike with mounts, and check the claimed 28 kg and 120 kg rider limit if you lift it or carry luggage. With the build pinned down, comparing current offers makes sense.
Pros
- Bosch Performance Line 65 Nm motor and 625 Wh battery on both current builds
- Official Tour EE Easy Entry frame with listed mudguards, lights, lock and kickstand
- Straightforward 1x gearing and 100 mm fork for paths and moderate trails
- Accessory mounts on the retailer 1x8 if you want to add your own commuting kit
Cons
- Approximately 28 kg claimed on the retailer build, so lifting and transport take effort
- No published UK rider-height or inseam bands
- A Touring label does not guarantee the official Tour EE equipment
The Rock Machine Torrent e50B is an aluminium Bosch mid-drive hardtail for commuting, leisure trips, cycle paths and moderate trails. How useful it is for touring depends on the build. It is a strong match if you want practical Bosch help on mixed surfaces and you are happy to check which bike a UK listing actually is.
Match each offer to the right bike
The latest official UK version is the Torrent e50-29 B Tour EE: an Easy Entry frame in S, M and L, a 1x9 11-46 drivetrain and listed mudguards, front and rear lights, an integrated lock and a kickstand.
A separate retailer-listed 625 Wh bike uses a microSHIFT Acolyte 1x8 12-46 drivetrain. An XL size is listed for that build. It lists accessory mounts and a kickstand. A Touring label on that listing does not make it the official Tour EE, so keep the two apart when you compare prices.
Older Torrent e50-29 B bikes are a 500 Wh generation. The standard build had a maximum 100 km claim, Shimano Altus 1x9 11-36 gearing and accessory mounts. The touring-equipped 500 Wh bike used 1x8 12-46 with mudguards, lights, lock and kickstand. Battery, gears and range claims all differ from the current 625 Wh bikes.
Motor, battery and range
Both current builds use a Bosch Performance Line motor rated at 65 Nm and an integrated Bosch PowerTube 625 Wh battery. The maximum-range claim is up to 150 km, which is a ceiling rather than an ordinary-use figure. Fork travel is 100 mm on both.
Touring kit versus a Touring label
If you want mudguards, lights, a lock and a kickstand already fitted, that package is listed on the official Tour EE. The retailer 1x8 confirms mudguard and pannier mounts plus a kickstand, so you can add commuting or luggage kit, but rack load and child-seat approval have to be confirmed separately. Rock Machine says Tour EE specifications can change, so check lights and the lock on the bike you would actually take home if they matter to you.
Fit, weight and getting about
Tour EE is published in S, M and L; the retailer offer is XL. There are no published UK rider-height or inseam bands, so confirm fit in person. The retailer build is claimed at approximately 28 kg and lists a 120 kg maximum rider weight. That is the stuff you feel on stairs, trains and car racks, and it matters if you add luggage. Replacement wheels need to match its QR fork and 135x9 rear spacing.
Reviews
Electric Bike Action in the Czech Republic tested a Torrent INT e50-29 B with Shimano Altus 1x9 from the 500 Wh generation. They found it pleasant, compact and straightforward for general riding, with limited battery, motor and gearing reserves on steep climbs. That is colour on the older platform, not a verdict on the current 625 Wh bikes.
