Begode T4 Features Overview

Begode’s T4 is the first 16″ suspension Wheel, packed with a battery pack/motor combo that would normally found in a large 18″ machine like the S18, V11, & Hero. While the initial introduction has seen its share of troubles related to the same motor slipping condition found on the earlier S22s, Begode has since changed their motor supplier from ZX to QS, resulting in improved reliability. In addition, the controller has been redesigned incorporating an addition 6 MOSFETS, from 18x to 24x, for improved contoller load-sharing. 

  • Package size & weight: dimensionally the T4 is 26H x 10.6W x 17.7L, making it one of the most compact suspension Wheels produced today, & 10lb lighter than the comparable Hero. For those who commute, in buildings with flights of stairs, these incremental pounds can make all the difference in practicality of ownership.  
  • Battery Improvements: in addition to the upgraded high-powered Samsung 40T battery packs [for our production], Begode has added some much needed BMS safety improvements that include temperature probes on the BMS, line-protocol communication with the controller, & short-circuit protection.

  

  • Durable Construction: compact, yet rugged metal frame construction, using improved stainless screws/bolts. The motor has a beefed up 50mm wide rim for better stability/tire fitting & greater resiliance against deformation & damage.
  • 100mm of Suspension Travel: despite the smaller size,there is up 100mm of vertical travel, 20mm more than the Master, EX20, & MasterPro. This T4 uses the latest 4d generation Begode shock, with adjustable rebound settings, maximum chamber pressure of 300psi, supporting loads of up to 285lb.
  • Choice of Tires: depending on your needs, Begode is offering the choice of a knobby/off-road tire J802, or a CST-1488 street tire—the original CST-1773 hybrid tire will be available later.
  • Standard equipment: there are some decent value-adds that are included as standard here: like the mug-guard, set of Powerpad, die-cast spiked pedals [shipped separately for initial production] integrated seat & the charger has been upgraded from a 100V/3A to a 5A for faster <3hr charging.

Begode MTen4 Battery Comparison between Samsung 40T & 50E Cells

The principles of battery selection on PEVs is complex, but can be distilled down to a general rule of ‘the smaller the battery pack, the more power is demanded from the cells’. The T4 battery pack is composed of 24 cells in series & 4 parallels (24s4p), the same configuration as the RS, Nikola+, etc. Since the surges in peak power output are greater than on the earlier generation hardware—more powerful controller & motor—it’s essential that the battery pack that matches the capabilities of the rest of the machine, minimize cell stresses & brown-out potential.  

While the new BMS architecture possesses improved safety mechanisms—temperature probes & short-protection—the hard lessons of history have demonstrated that latent fire risks may only be manifested years later. For this comparatively small machine, we deem it essential to require this model be equipped with a high-powered cell, the Samsung 40T. Beyond the safety/performance benefits, other advantages include: faster charging potential (up to 8-10A), superior pack longevity, cooler operation, increased performance, more efficient utilization of energy from the battery pack.
